The Washington Post confirmed tonight that a former FBI official, Mark Felt, was the confidential source known as “Deep Throat” who provided the newspaper information that led to former President Richard Nixon’s impeachment and eventual resignation.
The paper made its announcement on its website after Felt, 91 and living in California, talked to a lawyer who wrote a magazine article for Vanity Fair.
