Mark Felt, whose Deep Throat identity was revealed in 2005, has died, aged 95, at his home in Santa Rosa, California.
Felt was Associate Director of the Federal Bureau of Investigation (FBI) during the early period of Watergate. He started providing information and guidance to Washington Post journalist Bob Woodward in 1972.
Referred to initially as “my friend” by Woodward, Felt was nicknamed Deep Throat, a reference to a pornographic movie of the time.
