W. Mark Felt, 2005 News

former No. 2 official at the FBI, in May revealed himself to be “Deep Throat,” the anonymous source who leaked information to Washington Post reporters Carl Bernstein and Bob Woodward about the FBI investigation into the 1972 Watergate break-in. Ironically, it was Vanity Fair magazine, not the Post, that broke the story. Only after the magazine released the story did Woodward and Bernstein confirm that Felt was their source. The disclosure ended more than three decades of speculation and conjecture over Deep Throat's true identity. Felt, who is 91 and in poor health, did not say why he leaked the information. Some people have said it was out of a sense of responsibility, while others said it was out of anger that he was not chosen to succeed J. Edgar Hoover as director of the FBI.
