The Watergate scandal of the 1970s involved the burglary of the Democratic National Committee headquarters in the Watergate apartment complex in Washington D.C. by Republican operatives connected to President Richard Nixon's re-election campaign. Multiple investigations revealed that senior White House officials, including Nixon, were involved in attempting to cover-up the burglary and other abuses of power. Facing impeachment and criminal prosecution, Nixon resigned as president on August 9, 1974, becoming the only U.S. president to resign from office. His successor Gerald Ford later pardoned Nixon for any federal crimes he may have committed.
