What was the code name of the informant used by Woodward and Bernstein in the Watergate scandals?

Deep Throat in Watergate is the pseudonym given to the secret informant who provided information to Bob Woodward and Carl Bernstein of The Washington Post in 1972 about the involvement of U.S. President Richard Nixon's administration in what came to be known as the Watergate scandal. Watergate is the specific term used to describe a complex web of political scandals about the break-in (burglary) at the Democratic National Committee (DNC) headquarters at the Watergate office complex in Washington, D.C. in June 1972.

In 2005, 31 years after Nixon's resignation and 11 years after Nixon's death, a family attorney stated that former Federal Bureau of Investigation Associate Director Mark Felt was the informant, Deep Throat.

The Watergate scandal eventually led to the resignation of President Nixon as well as prison terms for White House Chief of Staff H. R. Haldeman, G. Gordon Liddy, Egil Krogh, White House Counsels Charles Colson, former United States Attorney General John N. Mitchell, John Dean, and presidential adviser John Ehrlichman.
