Mark Felt, the man who helped bring down President Richard Nixon as the infamous “Deep Throat” for investigative reporters Bob Woodward and Carl Bernstein, died at his Santa Rosa home Thursday, the Santa Rosa Press Democrat reports.

In 2005, more than 30 years after his whistle-blowing helped topple a presidency, Mark Felt, once a top FBI official, held a press conference on the front steps of his Santa Rosa home.

Felt, then 91, revealed that he was “Deep Throat,” the anonymous source who leaked information to Washington Post reporters about the Watergate scandal that eventually led to the resignation of President Richard Nixon in 1972. [More]
