Of the 48 vice presidents in US history, the office of the vice president has been vacated eighteen times. Only twice, by John Calhoon and Spiro Agnew, has the Vice President resigned. John Tyler, Millard Fillmore, Andrew Johnson, Chester Arthur, Theodore Roosevelt, Harry Truman, Lyndon Johnson, and Gerald Ford all assumed the office of President upon the death or resignation of the sitting President. The other nine Vice Presidents who vacated the office died while in office. Upon the passage of the 25th amendment, the President can nominate and the House and Senate confirm a new Vice President. This has only happened twice, when Spiro Agnew resigned and when Gerald Ford became President.
