Washington Post: "The Washington Post today confirmed that W. Mark Felt, a former number-two official at the FBI, was 'Deep Throat,' the secretive source who provided information that helped unravel the Watergate scandal in the early 1970s and contributed to the resignation of president Richard M. Nixon.

The confirmation came from Bob Woodward and Carl Bernstein, the two Washington Post reporters who broke the Watergate story, and their former top editor, Benjamin C. Bradlee."
