FBI agents soon established that hundreds of thousands of dollars in Nixon campaign contributions had been set aside to pay for a massive undercover anti-Democratic operation.

During an interview with the Senate select Watergate committee on July 16, 1973, former White House aide Alexander Butterfield revealed that Nixon had been taping all of his conversations and telephone calls in the White House since 1971. After losing a battle in the Supreme Court to keep these tapes private, Nixon was heard approving the cover-up of the Watergate burglary less than a week after it happened. During a June 20, 1972, discussion of the Watergate scandal between the President and former White House chief of staff H.R. Haldeman, an 18 1/4-minute gap had been inexplicably erased, causing frustration and speculation from investigators.
