Richard Nixon was elected president in 1968 and re-elected in a landslide in 1972. However, in June 1972 five men were arrested for breaking into the Democratic National Committee headquarters in the Watergate office complex. This began the Watergate scandal that eventually led to Nixon's resignation. Investigations by the Senate committee and a special prosecutor revealed Nixon's involvement in the cover-up of White House connections to the burglary. As more information came out through hearings and subpoenaed tapes, Nixon lost public and political support. He resigned in August 1974 before the House could impeach him to avoid almost certain removal from office.
