Vice President of the United States

The vice president of the United States (informally referred to as VP, or veep) is the second-highest officer in the executive branch of the U.S. federal government, after the president of the United States, and ranks first in the presidential line of succession. The vice president is also an officer in the legislative branch, as President of the Senate. In this capacity, the vice president presides over Senate deliberations (or delegates this task to a member of the Senate), but may not vote except to cast a tie-breaking vote. The vice president also presides over joint sessions of Congress.

The vice president is indirectly elected together with the president to a four-year term of office by the people of the United States through the Electoral College. Section 2 of the Twenty-fifth Amendment, ratified in 1967, created a mechanism for intra-term vice presidential succession, establishing that vice presidential vacancies will be filled by the president and confirmed by both houses of Congress. Previously, whenever a vice president had succeeded to the presidency or had died or resigned from office, the vice presidency remained vacant until the next presidential and vice presidential terms began.

The vice president is also a statutory member of the National Security Council, and the Board of Regents of the Smithsonian Institution. The Office of the Vice President assists and organises the vice president's official functions. The role of the vice presidency has changed dramatically since the office was created during the 1787 constitutional Convention. Especially over the past 100 years, the vice presidency has evolved into a position of domestic and foreign policy political power, and is now widely seen as an integral part of a president's administration. As the vice president's role within the executive branch has expanded, his role within the legislative branch has contracted; for example, he presides over the Senate only infrequently.

The Constitution does not expressly assign the vice presidency to any one branch, causing a dispute among scholars about which branch of government the office belongs to: 1) the executive branch; 2) the legislative branch; 3) both; or 4) neither. The modern view of the vice president as an officer of the executive branch (isolated almost totally from the legislative branch) is due in large part to the assignment of executive authority to the vice president by either the president or Congress.

Mike Pence of Indiana is the 48th and current vice president of the United States. He assumed office on January 20, 2017.

Origin
No mention of an office of vice president was made at the 1787 Constitutional Convention until near the end, when an 11-member committee on "Leftover Business" proposed a method of electing the chief executive (president). Delegates had previously considered the selection of the Senate's presiding officer, deciding that, "The Senate shall choose its own President," and had agreed that this official would be designated the executive's immediate successor. They had also considered the mode of election of the executive but had not reached consensus. This all changed on September 4, when the committee recommended that the nation's chief executive be elected by an Electoral College, with each state having a number of presidential electors equal to the sum of that state's allocation of representatives and senators.

The proposed presidential election process called for each state to choose members of the electoral college, who would use their discretion to select the candidates they individually viewed as best qualified. Recognizing that loyalty to one's individual state outweighed loyalty to the new federation, the Constitution's framers assumed that individual electors would be inclined to choose a candidate from their own state (a so-called "favorite son" candidate) over one from another. So they created the office of vice president and required that electors vote for two candidates, requiring that at least one of their votes must be for a candidate from outside the elector's state, believing that this second vote could be cast for a candidate of national character. Additionally, to guard against the possibility that some electors might strategically throw away their second vote in order to bolster their favorite son's chance of winning, it was specified that the first runner-up presidential candidate would become vice president. Creating this new office imposed a political cost on strategically discarded electoral votes, incentivizing electors to make their choices for president without resort to electoral gamesmanship and to cast their second ballot accordingly.

The resultant method of electing the president and vice president, spelled out in Article II, Section 1, Clause 3, allocated to each state a number of electors equal to the combined total of its Senate and House of Representatives membership. Each elector was allowed to vote for two people for president (rather than for both president and vice president), but could not differentiate between their first and second choice for the presidency. The person receiving the greatest number of votes (provided that it was an absolute majority of the whole number of electors) would be president, while the individual who received the next largest number of votes became vice president. If there were a tie for first or for second place, or if no one won a majority of votes, the president and vice president would be selected by means of contingent elections protocols stated in the clause.

The emergence of political parties and nationally coordinated election campaigns during the 1790s (which the Constitution's framers had not contemplated) soon frustrated this original plan. In the election of 1796, Federalist John Adams won the presidency, but his bitter rival, Democratic-Republican Thomas Jefferson came second and became vice president. Thus, the president and vice president were from opposing parties; and Jefferson used the vice presidency to frustrate the president's policies. Then, four years later, in the election of 1800, Jefferson, and fellow Democratic-Republican Aaron Burr each received 73 electoral votes. In the contingent election that followed, Jefferson finally won on the 36th ballot, and Burr became vice president. Afterward, the system was overhauled through the Twelfth Amendment in time to be used in the 1804 election.

Roles of the vice president
Although delegates approved establishing the office, with both its executive and senatorial functions, not many understood the office, and so they gave the vice president few duties and little power. Only a few states had an analogous position. Among those that did, New York's constitution provided that, "The lieutenant-governor shall, by virtue of his office, be president of the Senate, and, upon an equal division, have a casting voice in their decisions, but not vote on any other occasion." As a result, the vice presidency originally had authority in only a few areas. The present-day power of the office flows primarily from delegations from the president and Congress, as well as through constitutional amendments.

Preside over the United States Senate
Article I, Section 3, Clause 4 confers upon the vice president the title President of the Senate and authorizes him to preside over Senate meetings. In this capacity, the vice president is charged with maintaining order and decorum, recognizing members to speak, and interpreting the Senate's rules, practices, and precedent. The first two vice presidents, John Adams and Thomas Jefferson, both of whom gained the office by virtue of being runners-up in presidential contests, presided regularly over Senate proceedings, and did much to shape the role of Senate president. Several 19th century vice presidents—such as George Dallas, Levi Morton, and Garret Hobart—followed their example and led effectively, while others were rarely present.

With this position comes the authority to cast a tie-breaking vote. In practice, the number of times vice presidents have exercised this right has varied greatly. John C. Calhoun holds the record at 31 votes, followed closely by John Adams with 29. During his first year in office (through January 24, 2018), Mike Pence cast eight tie breaking votes; his predecessor, Joe Biden, did not cast any during his eight years in office.

As the framers of the Constitution anticipated that the vice president would not always be available to fulfil this responsibility, the Constitution provides that the Senate may elect a president pro tempore (or "president for a time") in order to maintain the proper ordering of the legislative process. In practice, since the early 20th century, the President of the Senate rarely presides, nor does the President pro tempore. He regularly delegates the task to other Senate members. Rule XIX, which governs debate, does not authorize the vice president to participate in debate, and grants only to members of the Senate (and, upon appropriate notice, former presidents of the United States) the privilege of addressing the Senate, without granting a similar privilege to the sitting vice president. Thus, Time magazine wrote in 1925, during the tenure of Vice President Charles G. Dawes, "once in four years the Vice President can make a little speech, and then he is done. For four years he then has to sit in the seat of the silent, attending to speeches ponderous or otherwise, of deliberation or humor."

Preside over impeachment trials
As President of the Senate he may also preside over most of the impeachment trials of federal officers. However, whenever the president of the United States is on trial, the Constitution requires that the Chief Justice of the United States must preside. This stipulation was designed to avoid the possible conflict of interest in having the vice president preside over the trial for the removal of the one official standing between him and the presidency. Curiously, the framers made no mention of who would preside in the instance where the vice president is the officer impeached; thus leaving a loophole whereby a vice president, as President of the Senate, could preside at their own impeachment trial.

Supervise electoral vote count
The Twelfth Amendment, like the superseded Article II clause, provides that the vice president, in his capacity as President of the Senate, also presides over counting and presentation of the votes of the Electoral College. This process occurs during a joint session of Congress held, as prescribed by federal statute, on January 6 of the year following the presidential election. It will next take place following the 2020 presidential election, on January 6, 2021 (unless Congress sets a different date by law). In this capacity, four vice presidents have been able to announce their own election to the presidency: John Adams, Thomas Jefferson, Martin Van Buren, and George H. W. Bush. Conversely, John C. Breckinridge, in 1861, Richard Nixon, in 1961, and Al Gore, in 2001, all had to announce their opponent's election. In 1969, Vice President Hubert Humphrey would have done so as well, following his 1968 loss to Richard Nixon; however, on the date of the Congressional joint session, Humphrey was in Norway attending the funeral of Trygve Lie, the first elected Secretary-General of the United Nations. The president pro tempore presided in his absence.

On February 8, 1933, Vice President Charles Curtis announced the election of his successor, House Speaker John Nance Garner, while Garner was seated next to him on the House dais.

Succession to the presidency


Article II, Section 1, Clause 6 stipulates that the vice president takes over the "powers and duties" of the presidency in the event of a president's removal, death, resignation, or inability. Even so, it does not clearly state whether the vice president became President of the United States or simply acted as president in a case of succession. Debate records from the 1787 Constitutional Convention, along with various participants' later writings on the subject, show that the framers of the Constitution intended that the vice president would temporarily exercise the powers and duties of the office in the event of a president's death, disability or removal, but not actually become President of the United States in their own right.

This understanding was first tested in 1841, following the death of President William Henry Harrison, only 8973 days days into his term. Harrison's vice president, John Tyler, asserted that he had succeeded to the office of president, not just to its powers and duties. He took the presidential oath of office, and declined to acknowledge documents referring to him as "Acting President." Although some in Congress denounced Tyler's claim as a violation of the Constitution, he adhered to his position. Tyler's view ultimately prevailed when the Senate and House voted to acknowledge him as president, setting a momentous precedent for an orderly transfer of presidential power following a president's death, one made explicit by Section 1 of the Twenty-fifth Amendment in 1967. In total, nine vice presidents have succeeded to the presidency intra-term. In addition to Tyler, they are Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, Lyndon B. Johnson, and Gerald Ford.

Presidential disabilities
Even after the precedent regarding presidential succession following a president's death was set, there remained ambiguity in the Article II succession clause regarding a disabled president. What constituted an "inability"? Who determined the existence of an inability? Did a vice president become president for the rest of the presidential term in the case of an inability; or was the vice president merely "acting as President"? During the 19th and first half of the 20th century several presidents experienced periods of severe illness, physical disability or injury, some lasting for weeks or months. During these times, even though the nation needed effective presidential leadership, no vice president wanted to seem like a usurper, and so power was never transferred. After President Dwight D. Eisenhower openly addressed his health issues and made it a point to enter into an agreement with Vice President Richard Nixon that provided for Nixon to act on his behalf in the event that Eisenhower became unable to provide effective presidential leadership (Nixon did informally assume some of the president's duties for several weeks on each of three occasions when Eisenhower was ill), discussions began in Congress about clearing-up the Constitution's ambiguity on the subject.

Sections 3 and 4 of the Twenty-fifth Amendment provide for situations where the president is temporarily unable to lead, such as if the president has a surgical procedure, becomes seriously ill or injured, or is otherwise unable to discharge the powers or duties of the presidency. Section 3 deals with self-declared incapacity, and Section 4 addresses incapacity declared by the joint action of the vice president and of a majority of the Cabinet. While Section 4 has never been invoked, Section 3 has been invoked on three occasions by two presidents. President Ronald Reagan did so once, on July 13, 1985, before undergoing surgery – Vice President George H. W. Bush was acting president for approximately eight hours. President George W. Bush did so twice, on June 29, 2002, and July 21, 2007, prior to undergoing medical procedures, which were done under sedation – Vice President Dick Cheney was acting president for approximately two hours on each occasion.

Informal roles
The extent of any informal roles and functions of the vice president depend on the specific relationship between the president and the vice president, but often include tasks such as drafter and spokesperson for the administration's policies, adviser to the president, and being a symbol of American concern or support. The influence of the vice president in this role depends almost entirely on the characteristics of the particular administration. Dick Cheney, for instance, was widely regarded as one of President George W. Bush's closest confidants. Al Gore was an important adviser to President Bill Clinton on matters of foreign policy and the environment.

Under the American system of government the president is both head of state and head of government, and the ceremonial duties of the former position are often delegated to the vice president. The vice president will on occasion represent the president and the U.S. government at state funerals abroad, or at various events in the United States. This often is the most visible role of the vice president. The vice president may also meet with other heads of state at times when the administration wishes to demonstrate concern or support but cannot send the president personally.

Eligibility
To be Constitutionally eligible to serve as the nation's vice president, a person must, according to the Twelfth Amendment, meet the eligibility requirements to become president (which are stated in Article II, Section 1, Clause 5). Thus, to serve as vice president, an individual must:
 * be a natural-born U.S. citizen;
 * be at least 35 years old;
 * be a resident in the U.S. for at least 14 years.

A person who meets the above qualifications is still disqualified from holding the office of vice president under the following conditions:
 * Under Article I, Section 3, Clause 7, upon conviction in impeachment cases, the Senate has the option of disqualifying convicted individuals from holding federal office, including that of vice president;
 * Under Section 3 of the Fourteenth Amendment, no person who has sworn an oath to support the Constitution, who has later gone to war against the United States, or given aid and comfort to the nation's enemies can serve in a state or federal office – including as vice president. This disqualification, originally aimed at former supporters of the Confederacy, may be removed by a two-thirds vote of each house of the Congress.

Nominating process
Though the vice president does not need to have any political experience, most major-party vice presidential nominees are current or former United States senators or representatives, with the occasional nominee being a current or former governor, a high-ranking military officer, or a holder of a major post within the Executive Department. The vice presidential candidates of the major national political parties are formally selected by each party's quadrennial nominating convention, following the selection of the party's presidential candidate. The official process is identical to the one by which the presidential candidates are chosen, with delegates placing the names of candidates into nomination, followed by a ballot in which candidates must receive a majority to secure the party's nomination.

In practice, the presidential nominee has considerable influence on the decision, and in the 20th century it became customary for that person to select a preferred running mate, who is then nominated and accepted by the convention. In recent years, with the presidential nomination usually being a foregone conclusion as the result of the primary process, the selection of a vice presidential candidate is often announced prior to the actual balloting for the presidential candidate, and sometimes before the beginning of the convention itself. The first presidential aspirant to announce his selection for vice president before the beginning of the convention was Ronald Reagan who, prior to the 1976 Republican National Convention announced that Richard Schweiker would be his running mate. Reagan's supporters then sought to amend the convention rules so that Gerald R. Ford would be required to name his vice presidential running mate in advance as well. The proposal was defeated, and Reagan did not receive the nomination in 1976. Often, the presidential nominee will name a vice presidential candidate who will bring geographic or ideological balance to the ticket or appeal to a particular constituency.

The vice presidential candidate might also be chosen on the basis of traits the presidential candidate is perceived to lack, or on the basis of name recognition. To foster party unity, popular runners-up in the presidential nomination process are commonly considered. While this selection process may enhance the chances of success for a national ticket, in the past it often insured that the vice presidential nominee represented regions, constituencies, or ideologies at odds with those of the presidential candidate. As a result, vice presidents were often excluded from the policy-making process of the new administration. Many times their relationships with the president and his staff were aloof, non-existent, or even adversarial.

The ultimate goal of vice presidential candidate selection is to help and not hurt the party's chances of getting elected; nonetheless, several vice presidential selections have been controversial. In 1984, Democratic nominee Walter Mondale's groundbreaking choice of Geraldine Ferraro as his running mate (the first woman in U.S. history nominated for vice president by a major political party), became a drag on the ticket due to repeated questions about her husband's finances. A selection whose positive traits make the presidential candidate look less favorable in comparison or which can cause the presidential candidate's judgment to be questioned often backfire, such as in 1988 when Democratic candidate Michael Dukakis chose experienced Texas Senator Lloyd Bentsen; Bentsen was considered a more seasoned statesman in federal politics and somewhat overshadowed Dukakis. Questions about Dan Quayle's experience were raised in the 1988 presidential campaign of George H. W. Bush, but the Bush-Quayle ticket still won handily. James Stockdale, the choice of third-party candidate Ross Perot in 1992, was seen as unqualified by many and Stockdale had little preparation for the vice presidential debate, but the Perot-Stockdale ticket still won about 19% of the vote. In 2008, Republican John McCain chose Sarah Palin as his running mate over his primary rivals and/or campaign surrogates such as Mitt Romney or Tom Ridge. This surprise move would, it was hoped, draw women voters disappointed by Hillary Clinton's defeat in the Democratic presidential primaries into the McCain camp. Palin's selection soon came to be seen as a negative for McCain, due to her several controversies during her gubernatorial tenure which were highlighted by the press, and her feuding with McCain campaign chairman Steve Schmidt. This perception continued to grow throughout the campaign, especially after her interviews with Katie Couric led to concerns about her fitness for the presidency.

Historically, vice presidential candidates were chosen to provide geographic and ideological balance to a presidential ticket, widening a presidential candidate's appeal to voters from outside his regional base or wing of the party. Candidates from electoral-vote rich states were usually preferred. However, in 1992, moderate Democrat Bill Clinton (of Arkansas) chose moderate Democrat Al Gore (of Tennessee) as his running mate. Despite the two candidates' near-identical ideological and regional backgrounds, Gore's extensive experience in national affairs enhanced the appeal of a ticket headed by Clinton, whose political career had been spent entirely at the local and state levels of government. In 2000, George W. Bush chose Dick Cheney of Wyoming, a reliably Republican state with only three electoral votes, and in 2008, Barack Obama mirrored Bush's strategy when he chose Joe Biden of Delaware, a reliably Democratic state, likewise one with only three electoral votes. Both Cheney and Biden were chosen for their experience in national politics (experience lacked by both Bush and Obama) rather than the ideological balance or electoral vote advantage they would provide.

Prior to the 2000 election, both George W. Bush and Dick Cheney lived in and voted in Texas. While nothing in the Constitution prohibits a presidential candidate and his or her running mate being from the same state, the "inhabitant clause" of the Twelfth Amendment does mandate that every presidential elector must cast a ballot for at least one candidate who is not from their own state. To avoid creating a potential problem for Texas' electors, Cheney changed his residency back to Wyoming prior to the campaign.

The first presidential candidate to choose his vice presidential candidate was Franklin D. Roosevelt in 1940. The last not to name a vice presidential choice, leaving the matter up to the convention, was Democrat Adlai Stevenson in 1956. The convention chose Tennessee Senator Estes Kefauver over Massachusetts Senator (and later president) John F. Kennedy. At the tumultuous 1972 Democratic convention, presidential nominee George McGovern selected Senator Thomas Eagleton as his running mate, but numerous other candidates were either nominated from the floor or received votes during the balloting. Eagleton nevertheless received a majority of the votes and the nomination, though he later resigned from the ticket, resulting in Sargent Shriver becoming McGovern's final running mate; both lost to the Nixon-Agnew ticket by a wide margin, carrying only Massachusetts and the District of Columbia.

In cases where the presidential nomination is still in doubt as the convention approaches, the campaigns for the two positions may become intertwined. In 1976, Ronald Reagan, who was trailing President Gerald R. Ford in the presidential delegate count, announced prior to the Republican National Convention that, if nominated, he would select Senator Richard Schweiker as his running mate. This move backfired to a degree, as Schweiker's relatively liberal voting record alienated many of the more conservative delegates who were considering a challenge to party delegate selection rules to improve Reagan's chances. In the end, Ford narrowly won the presidential nomination and Reagan's selection of Schweiker became moot.

In the 2008 Democratic presidential primaries which pitted Hillary Clinton against Barack Obama, Clinton suggested a Clinton-Obama ticket with Obama in the vice president slot as it would be "unstoppable" against the presumptive Republican nominee. Obama rejected the offer outright saying "I want everybody to be absolutely clear. I'm not running for vice president. I'm running for president of the United States of America" while noting "With all due respect. I won twice as many states as Sen. Clinton. I've won more of the popular vote than Sen. Clinton. I have more delegates than Sen. Clinton. So, I don't know how somebody who's in second place is offering vice presidency to the person who's in first place". Obama stated that the nomination process would have to be a choice between himself and Clinton, saying "I don't want anybody here thinking that 'Somehow, maybe I can get both'", by nominating Clinton as president and assuming he would be her running mate". Some suggested that it was a ploy by the Clinton campaign to denigrate Obama as less qualified for the presidency. Later, when Obama became the presumptive Democratic nominee, former president Jimmy Carter cautioned against Clinton being picked for the vice president slot on the ticket, saying "I think it would be the worst mistake that could be made. That would just accumulate the negative aspects of both candidates", citing opinion polls showing 50% of US voters with a negative view of Hillary Clinton.

Election


The vice president is elected indirectly by the voters of each state and the District of Columbia through the Electoral College, a body of electors formed every four years for the sole purpose of electing the president and vice president to concurrent four-year terms. Each state is entitled to a number of electors equal to the size of its total delegation in both houses of Congress. Additionally, the Twenty-third Amendment provides that the District of Columbia is entitled to the number it would have if it were a state, but in no case more than that of the least populous state. Currently, all states and D.C. select their electors based on a popular election held on Election Day. In all but two states, the party whose presidential-vice presidential ticket receives a plurality of popular votes in the state has its entire slate of elector nominees chosen as the state's electors. Maine and Nebraska deviate from this winner-take-all practice, awarding two electors to the statewide winner and one to the winner in each congressional district.

On the first Monday after the second Wednesday in December, about six weeks after the election, the electors convene in their respective states (and in Washington D.C.) to vote for president and, on a separate ballot, for vice president. The certified results are opened and counted during a joint session of Congress, held in the first week of January. A candidate who receives an absolute majority of electoral votes for vice president (currently 270 of 538) is declared the winner. If no candidate has a majority, the Senate must meet to elect a vice president using a contingent election procedure in which senators, casting votes individually, choose between the two candidates who received the most electoral votes for vice president. For a candidate to win the contingent election, he or she must receive votes from an absolute majority of senators (currently 51 of 100).

There has been only one vice presidential contingent election since the process was created by the Twelfth Amendment. It occurred on February 8, 1837, after no candidate received a majority of the electoral votes cast for vice president in the 1836 election. By a 33–17 vote, Richard M. Johnson (Martin Van Buren's running mate) was elected the nation's ninth vice president over Francis Granger.

Inauguration


Pursuant to the Twentieth Amendment, the vice president's term of office begins at noon on January 20, as does the president's. The first presidential and vice presidential terms to begin on this date, known as Inauguration Day, were the second terms of President Franklin D. Roosevelt and Vice President John Nance Garner in 1937. Previously, Inauguration Day was on March 4. As a result of the date change, the first term (1933–37) of both men had been shortened by 43 days days.

Also in 1937, the vice president's swearing-in ceremony was held on the Inaugural platform on the Capitol's east front immediately before the president's swearing in. Up until then, most vice presidents took the oath of office in the Senate chamber, prior to the president's swearing-in ceremony. Although the Constitution contains the specific wording of the presidential oath, it only contains a general requirement, in Article VI, that the vice president and other government officers shall take an oath or affirmation to support the Constitution. The current form, which has been used since 1884 reads:

"I, (first name last name), do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God."

Term of office
The term of office for both the vice president and the president is four years. While the Twenty-Second Amendment generally restricts the president to two terms, there is no such limitation on the office of vice president, meaning an eligible person could hold the office as long as voters continued to vote for electors who in turn would reelect the person to the office; one could even serve under different presidents. This has happened twice: George Clinton (1805–1812) served under both Thomas Jefferson and James Madison; and John C. Calhoun (1825–1832) served under John Quincy Adams and Andrew Jackson. Additionally, neither the Constitution's eligibility provisions nor the Twenty-second Amendment's presidential term limit explicitly disqualify a twice-elected president from serving as vice president. As of the 2016 election cycle however, no former president has tested the amendment's legal restrictions or meaning by running for the vice presidency.

Impeachment
Article II, Section 4 of the Constitution allows for the removal of federal officials, including the vice president, from office for "treason, bribery, or other high crimes and misdemeanors." Article I, Section 2, Clause 5 authorizes the House of Representatives to serve as a "grand jury" with the power to impeach said officials by a majority vote. Article I, Section 3, Clause 6 authorizes the Senate to serve as a court with the power to remove impeached officials from office, by a two-thirds vote to convict. No vice president has ever been impeached.

Salary
The vice president's salary is $235,100. The salary was set by the 1989 Government Salary Reform Act, which also provides an automatic cost of living adjustment for federal employees. The vice president does not automatically receive a pension based on that office, but instead receives the same pension as other members of Congress based on his position as President of the Senate. The vice president must serve a minimum of two years to qualify for a pension.

Residence
The home of the vice president was only designated in 1974, when Congress established Number One Observatory Circle as the official temporary residence of the vice president of the United States. In 1966 Congress, concerned about safety and security and mindful of the increasing responsibilities of the office, allotted monies ($75,000) to fund construction of a residence for the vice president, but implementation stalled and after eight years the decision was revised, and One Observatory Circle was then designated for the vice president. Up until the change, vice presidents lived in homes, apartments, or hotels, and were compensated more like cabinet members and members of Congress, receiving only a housing allowance.

The three-story Queen Anne style mansion was built in 1893 on the grounds of the U.S. Naval Observatory in Washington, D.C., to serve as residence for the superintendent of the Observatory. In 1923, the residence was reassigned to be the home of the Chief of Naval Operations (CNO), which it was until it was turned over to the office of the vice president fifty years later.

Office as stepping stone to the presidency
In recent decades, the vice presidency has frequently been used as a platform to launch bids for the presidency. The transition of the office to its modern stature occurred primarily as a result of Franklin Roosevelt's 1940 nomination, when he captured the ability to nominate his running mate instead of leaving the nomination to the convention. Prior to that, party bosses often used the vice presidential nomination as a consolation prize for the party's minority faction. A further factor potentially contributing to the rise in prestige of the office was the adoption of presidential preference primaries in the early 20th century. By adopting primary voting, the field of candidates for vice president was expanded by both the increased quantity and quality of presidential candidates successful in some primaries, yet who ultimately failed to capture the presidential nomination at the convention.

Of the thirteen presidential elections from 1956 to 2004, nine featured the incumbent president; the other four (1960, 1968, 1988, 2000) all featured the incumbent vice president. Former vice presidents also ran in 1984 (Walter Mondale) and in 1968 (Richard Nixon, against the incumbent vice president, Hubert Humphrey). The presidential election of 2008 was the first presidential election since 1928 that saw neither an incumbent president nor an incumbent or former vice president take part in any primary or general election for the presidency on a major party ticket. Nixon is the only vice president to have been elected president while not an incumbent, as well as the only person elected twice to both the presidency and vice presidency.

Vacancies
Prior to ratification of the Twenty-fifth Amendment in 1967, no constitutional provision existed for filling an intra-term vacancy in the vice presidency. As a result, when one occurred, the office was left vacant until filled through the next ensuing election and inauguration. Between 1812 and 1967, the vice presidency was vacant on sixteen occasions—as a result of seven deaths, one resignation, and eight cases in which the vice president succeeded to the presidency.

Section 2 of the Twenty-fifth Amendment established a procedure for filling such a vacancy:

"Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress."

This procedure has been implemented twice since the amendment came into force. The first instance occurred in 1973 following the October 10 resignation of Spiro Agnew, when Gerald Ford was nominated by President Richard Nixon and confirmed by Congress. The second occurred 10 months later following Ford's August 9, 1974 accession to the presidency upon Nixon's resignation, when Nelson Rockefeller was nominated by President Ford and confirmed by Congress. Had it not been for this new constitutional mechanism, the vice presidency would have remained vacant after Agnew's resignation and Speaker of the House Carl Albert would have become Acting President when Nixon resigned, under the terms of the Presidential Succession Act of 1947.

Growth of the office
For much of its existence, the office of vice president was seen as little more than a minor position. John Adams, the first vice president, was the first of many frustrated by the "complete insignificance" of the office. To his wife Abigail Adams wrote, "My country has in its wisdom contrived for me the most insignificant office that ever the invention of man ... or his imagination contrived or his imagination conceived; and as I can do neither good nor evil, I must be borne away by others and met the common fate." John Nance Garner, who served as vice president from 1933 to 1941 under President Franklin D. Roosevelt, claimed that the vice presidency "isn't worth a pitcher of warm piss." Harry Truman, who also served as vice president under Roosevelt, said that the office was as "useful as a cow's fifth teat."

Thomas R. Marshall, the 28th vice president, lamented: "Once there were two brothers. One ran away to sea; the other was elected Vice President of the United States. And nothing was heard of either of them again." His successor, Calvin Coolidge, was so obscure that Major League Baseball sent him free passes that misspelled his name, and a fire marshal failed to recognize him when Coolidge's Washington residence was evacuated.

When the Whig Party asked Daniel Webster to run for the vice presidency on Zachary Taylor's ticket, he replied "I do not propose to be buried until I am really dead and in my coffin." This was the second time Webster declined the office, which William Henry Harrison had first offered to him. Ironically, both of the presidents making the offer to Webster died in office, meaning the three-time presidential candidate could have become president if he had accepted either. Since presidents rarely died in office, however, the better preparation for the presidency was considered to be the office of Secretary of State, in which Webster served under Harrison, Tyler, and later, Taylor's successor, Fillmore.

In the first 100 years of the United States no fewer than seven proposals to amend the constitution to abolish the office of vice president were advanced in the United States Congress. The first such amendment was presented by Samuel W. Dana in 1800 and was defeated by a vote of 27 to 85 in the United States House of Representatives. A second proposed amendment, introduced by United States Senator James Hillhouse in 1808 was also defeated. During the late-1860s and 1870s, five additional amendments were proposed. One supporter of the proposals, James Mitchell Ashley, opined that the office of vice president was "superfluous" and dangerous.

Garret Hobart, the first vice president under William McKinley, was one of the very few vice presidents at this time who played an important role in the administration. A close confidant and adviser of the president, Hobart was called "Assistant President." However, until 1919, vice presidents were not included in meetings of the President's Cabinet. This precedent was broken by President Woodrow Wilson when he asked Thomas R. Marshall to preside over Cabinet meetings while Wilson was in France negotiating the Treaty of Versailles. President Warren G. Harding also invited his vice president, Calvin Coolidge, to meetings. The next vice president, Charles G. Dawes, did not seek to attend Cabinet meetings under President Coolidge, declaring that "the precedent might prove injurious to the country." Vice President Charles Curtis was also precluded from attending by President Herbert Hoover.

In 1933, Franklin D. Roosevelt raised the stature of the office by renewing the practice of inviting the vice president to cabinet meetings, which every president since has maintained. Roosevelt's first vice president, John Nance Garner, broke with him over the "court-packing" issue, early in his second term, and became Roosevelt's leading critic. At the start of that term, on January 20, 1937, Garner had been the first vice president to be sworn into office on the Capitol steps in the same ceremony with the president; a tradition that continues. Prior to that time, vice presidents were traditionally inaugurated at a separate ceremony in the Senate chamber. Gerald R. Ford and Nelson A. Rockefeller, who were both appointed to the office under the terms of the 25th amendment, were inaugurated in the House and Senate chambers, respectively.

Henry Wallace, Roosevelt's vice president during his third term (1941–1945), was given major responsibilities during World War II. However, after numerous policy disputes between Wallace and other Roosevelt Administration and Democratic Party officials, he was denied renomination to office at the 1944 Democratic National Convention. Harry Truman was selected instead. During his 8973 days day vice presidency, Truman was not informed about any war or post-war plans, including the Manhattan Project, leading Truman to remark, wryly, that the job of the vice president was to "go to weddings and funerals." As a result of this experience, Truman, after succeeding to the presidency upon Roosevelt's death, recognized the need to keep the vice president informed on national security issues. Congress made the vice president one of four statutory members of the National Security Council in 1949.

The stature of the vice presidency grew again while Richard Nixon was in office (1953–1961). He attracted the attention of the media and the Republican party, when Dwight Eisenhower authorized him to preside at Cabinet meetings in his absence. Nixon was also the first vice president to formally assume temporary control of the executive branch, which he did after Eisenhower suffered a heart attack on September 24, 1955, ileitis in June 1956, and a stroke in November 1957.

Until 1961, vice presidents had their offices on Capitol Hill, a formal office in the Capitol itself and a working office in the Russell Senate Office Building. Lyndon B. Johnson was the first vice president to be given an office in the White House complex, in the Old Executive Office Building. The former Navy Secretary's office in the OEOB has since been designated the "Ceremonial Office of the Vice President" and is today used for formal events and press interviews. President Jimmy Carter was the first president to give his vice president, Walter Mondale, an office in the West Wing of the White House, which all vice presidents have since retained. Because of their function as Presidents of the Senate, vice presidents still maintain offices and staff members on Capitol Hill.

Though Walter Mondale's tenure was the beginning of the modern day power of the vice presidency, the tenure of Dick Cheney saw a rapid growth in the office of the vice president. Vice President Cheney held a tremendous amount of power and frequently made policy decisions on his own, without the knowledge of the president. During the 2008 presidential campaign, both vice presidential candidates, Sarah Palin and Joe Biden, stated the office had expanded too much under Cheney's tenure and both claimed they would reduce the role to simply being an adviser to the president. This rapid growth has led to calls for abolition of the vice presidency from various constitutional scholars and political commentators such as: Arthur M. Schlesinger Jr., Matthew Yglesias, and Bruce Ackerman.

Post-vice presidency
There are currently (since November 30, 2018) five living former vice presidents. In order of service they are:

Since 1977, former presidents and vice presidents who are elected or re-elected to the Senate are entitled to the largely honorific position of Deputy President pro tempore. To date, the only former vice president to have held this title is Hubert Humphrey following his return to the Senate. Also, under the terms of an 1886 Senate resolution, all former vice presidents are entitled to a portrait bust in the Senate wing of the United States Capitol, commemorating their service as presidents of the Senate. Dick Cheney is the most recent former vice president to be so honored.

Unlike former presidents, whose pension is fixed at the same rate, regardless of their time in office, former vice presidents receive their retirement income based on their role as President of the Senate. Additionally, since 2008, each former vice president and his immediate family is entitled (under the "Former Vice President Protection Act of 2008") to Secret Service protection for up to six months after leaving office, and again temporarily at any time thereafter if warranted.
