"The Watergate scandal began early in the morning of June 17, 1972, when several burglars were arrested in the office of the Democratic National Committee, located in the Watergate complex of buildings in Washington, D.C. This was no ordinary robbery: The prowlers were connected to President Richard Nixon’s reelection campaign, and they had been caught wiretapping phones and stealing documents. Nixon took aggressive steps to cover up the crime afterwards, and in August 1974, after his role in the conspiracy was revealed, Nixon resigned." -source https://www.history.com/topics/watergate
