Ex-FBI official: 'I'm Deep Throat' From MSNBC: "W. Mark Felt, who retired from the FBI after rising to its second most senior position, has identified himself as the "Deep Throat" source quoted by The Washington Post to break the Watergate scandal that led to President Nixon's resignation, Vanity Fair magazine said Tuesday."
Here's an advance copy (PDF) of the Vanity Fair article. Where'd I get access to it, you ask? Sorry, I can't reveal my sources.
Update (June 1, 2005): All the Deep Throat news you can swallow and more is being served over at Romenesko.
