The Watergate Scandal involved the June 17, 1972 break-in at the Democratic National Committee headquarters at the Watergate office complex in Washington D.C. by five men associated with President Nixon's re-election committee. This led to a Senate investigation and the revelation that President Nixon had an audio taping system in the White House. After fighting to prevent the release of the tapes, Nixon resigned in August 1974 when the House Judiciary Committee approved articles of impeachment, making him the only U.S. president to resign from office.
