who was deep throat in the watergate investigation

The secret informant known as "Deep Throat" in the Watergate investigation was Mark Felt. He was the associate director and the second-highest-ranking official at the FBI during the early 1970s. Felt provided critical information to Washington Post reporters Bob Woodward and Carl Bernstein, which was instrumental in uncovering the Watergate scandal and implicating the Nixon White House. He revealed his identity as Deep Throat in 2005, decades after the scandal broke and after Nixon's resignation.
