The Watergate scandal was a political scandal in the United States involving the administration of U.S. President Richard Nixon from 1971 to 1974 that led to Nixon's resignation. The scandal stemmed from the Nixon administration's continuous attempts to cover up its involvement in the June 17, 1972 break-in of the Democratic National Committee headquarters at the Washington, D.C. Watergate Office Building. After the five perpetrators were arrested, the press and the U.S. Justice Department connected the cash found on them at the time to the Nixon re-election campaign committee. Further investigations, along with revelations during subsequent trials of the burglars, led the U.S. House of Representatives to grant its judiciary committee additional investigation authority to probe into "certain matters within its jurisdiction", and the U.S. Senate to create a special investigative committee. The resulting Senate Watergate hearings were broadcast "gavel-to-gavel" nationwide by PBS and aroused public interest. Witnesses testified that the president had approved plans to cover up administration involvement in the break-in, and that there was a voice-activated taping system in the Oval Office. Throughout the investigation, the administration resisted its probes, which led to a constitutional crisis.
