deep throat

W. Mark Felt, a former associate director of the US Federal Bureau of Investigation, was the main whistleblower during the Watergate scandal of the 1970s. He recently revealed himself to be the mysterious source known as "Deep Throat" who assisted Washington Post reporters Bob Woodward and Carl Bernstein in their investigation into the scandal. His identity was kept secret for more than thirty years, until he revealed it himself in an article in Vanity Fair magazine. On May 31, 2005, Woodward, Bernstein and their chief editor at the time, Benjamin Bradlee, confirmed his claim to be true. Because of the scandal, Richard Nixon resigned as President and several White House aides ended up serving prison terms.
