The Washington Post picked up on the story; reporters Carl Bernstein and Bob Woodward relied on an informant known as "Deep Throat"—later revealed to be Mark Felt, associate director at the FBI—to link the men to the Nixon administration. Nixon downplayed the scandal as mere politics, calling news articles biased and misleading. A series of revelations made it clear that the Committee to Re-elect President Nixon, and later the White House, were involved in attempts to sabotage the Democrats. Senior aides such as White House Counsel John Dean faced prosecution; in total 48 officials were convicted of wrongdoing.[127][233][234]

Demonstrator demands impeachment, October 1973
In July 1973, White House aide Alexander Butterfield testified under oath to Congress that Nixon had a secret taping system and recorded his conversations and phone calls in the Oval Office. These tapes were subpoenaed by Watergate Special Counsel Archibald Cox; Nixon provided transcripts of the conversations but not the actual tapes, citing executive privilege. With the White House and Cox at loggerheads, Nixon had Cox fired in October in the "Saturday Night Massacre"; he was replaced by Leon Jaworski.
