The Watergate scandal was a major political scandal in the United States involving the administration of President Richard Nixon which began in 1972 and ultimately led to Nixon's resignation in 1974. It revolved around members of a group associated with Nixon's 1972 re-election campaign breaking into and planting listening devices in the Democratic National Committee headquarters at the Watergate Office Building in Washington, D.C., on June 17, 1972, and Nixon's later attempts to hide his administration's involvement.
