Vanity Fair reveals that Mark Felt was "Deep Throat".

Deep Throat is the pseudonym given to the secret informant who provided information in 1972 to Bob Woodward, who shared it with Carl Bernstein. Woodward and Bernstein were reporters for The Washington Post, and Deep Throat provided key details about the involvement of U.S. president Richard Nixon's administration in what came to be known as the Watergate scandal. In 2005, 31 years after Nixon's resignation and 11 years after Nixon's death, a family attorney stated that former Federal Bureau of Investigation (FBI) Associate Director Mark Felt was Deep Throat. By then, Felt was suffering from dementia and had previously denied being Deep Throat, but Woodward and Bernstein then confirmed the attorney's claim.

Vanity Fair is a monthly magazine of popular culture, fashion, and current affairs published by Condé Nast in the United States.

The first version of Vanity Fair was published from 1913 to 1936. The imprint was revived in 1983 and currently includes five international editions of the magazine. As of 2018, the Editor-in-Chief is Radhika Jones.
