“DEEP THROAT” The major symbol of twentieth-century investigative journalism, Carl Bernstein and Bob Woodward’s (above right) coverage of the Watergate scandal for the Washington Post helped topple the Nixon White House. In All the President’s Men, the newsmen’s book about their investigation, a major character is Deep Throat, the key unidentified source for much of Woodward’s reporting. Deep Throat’s identity was protected by the two reporters for more than thirty years. Then, in summer 2005, he revealed himself as Mark Felt (above), the former No. 2 official in the FBI during the Nixon administration. (Felt died in 2008.)
