How Many Presidents Have Resigned
Only one U.S. president has resigned from office. Richard Nixon left the presidency on August 9, 1974, becoming the first and only president to do so. The number of presidents who resigned stands at one out of 46 presidencies. This fact is confirmed by the National Archives and the official list of U.S. presidents maintained by the White House Historical Association. The single resignation shaped modern views on presidential accountability and the 25th Amendment.
The resignation followed the Watergate scandal, a major political crisis that began with a break-in at the Democratic National Committee headquarters. Investigative reporting by journalists and congressional hearings revealed a chain of abuses of power, cover-ups, and misuse of government agencies. The House Judiciary Committee approved articles of impeachment, and the release of the Nixon tapes showed direct involvement in the obstruction of justice. Facing near-certain impeachment and removal, Nixon chose to resign rather than face a Senate trial.
Key Details of the Nixon Resignation
Timeline and Immediate Outcome
Nixon announced his resignation in a televised address on the evening of August 8, 1974, and left office the next day. Gerald Ford, the vice president at the time, immediately succeeded him as the 38th president. Ford then issued a full and unconditional pardon for any crimes Nixon may have committed while in office. The transition was handled according to the constitutional line of succession and the provisions of the 25th Amendment, which clarified the process for filling a vacant vice presidency.
Political and Institutional Impact
The resignation triggered a crisis of public trust in the executive branch and led to lasting reforms in campaign finance, ethics, and intelligence oversight. Congress passed the Ethics in Government Act, the Foreign Intelligence Surveillance Act, and strengthened the Freedom of Information Act. The event is frequently cited in discussions about the limits of presidential power, the role of the media, and the independence of the Department of Justice. It remains the only case in U.S. history where a president left office through resignation rather than election loss or death.
Why Only One President Resigned
Despite numerous political scandals, investigations, and impeachment proceedings, no other president has resigned. Several presidents faced impeachment inquiries or votes, but none were removed by the Senate. The rarity of the Nixon resignation is partly due to the high political cost of leaving office voluntarily, the lack of a clear exit path before the 25th Amendment, and the strength of constitutional norms. The number of presidents who resigned remains one, while the number removed by impeachment stands at zero.
Impeachment is a formal process by the House of Representatives, but removal requires a two-thirds vote in the Senate. Presidents Andrew Johnson and Bill Clinton were impeached by the House but acquitted by the Senate. Donald Trump was impeached twice by the House but acquitted both times by the Senate. These outcomes show that the constitutional threshold for removal is high, which may explain why resignation has been used only once, even during periods of intense political polarization and scandal.
Comparison With Other Forms of Presidential Exit
Death, Election Loss, and Term Limits
Four presidents died in office, four were succeeded after losing reelection, and one was removed by impeachment in a later proceeding. The 22nd Amendment limits presidents to two elected terms, and no president has served more than that since its ratification. The single resignation is distinct from these exits because it is a voluntary departure under pressure, not a constitutional limit or a judicial removal. This makes the case unique in the historical record and a key reference point in studies of executive power and political accountability.
Global Context and Constitutional Design
In other democracies, heads of state have resigned under pressure from parliaments, courts, or popular movements, but the U
