Deep Throat

Akaeli, I assume you mean "DT"? He's supposedly the source of the condemning evidence that got Nixon in all that trouble about breaking into the DNC HQ. Woodward and Bernstein interviewed him/her many times to gain information for their book, "All the President's Men" which documented how it all went down. There's been speculation for decades on who the source is that brought down Nixon, and Woodward has promised keep DT's identity secret until he dies (so someone doesn't go around and try to knock him off, fire him, or whatever.)
