William Mark Felt, Sr. (August 17, 1913 – December 18, 2008), a former Associate Director of the FBI, was "Deep Throat," a source of much of the Watergate scandal information. He was the highest-ranking federal agent ever convicted of wrongdoing. He had authorized raids on homes of suspected Weather Underground terrorists without receiving search warrants, for which he was pardoned during the appeals process by US President Ronald Reagan.
