Nancy Pelosi, not for the first time, alluded to dirt she has on Newt Gingrich during an interview with CNN's John King Tuesday night.  On Wednesday, Gingrich sounded really annoyed about it. Just before the State of the Union address on Tuesday, Pelosi told King that Newt was "not going to be president of the United States," because, "There's something I know." Ominous! And it really irked Gingrich, who sounded exasperated on the Today show Wednesday. Politico has his comments from that appearance: "She lives in a San Francisco environment of strange fantasies and strange understandings of reality. I have no idea what’s in Nancy Pelosi’s head. If she knows something, spit it out. Tell us what it is. I have no idea what she’s talking about."

As we noted, Pelosi's made this vague threat before, and she really seems to enjoy holding whatever she allegedly knows over Gingrich's head. Back in December, she told Talking Points Memo's Brian Beutler she had all kinds of dirt on him: “One of these days we’ll have a conversation about Newt Gingrich... I know a lot about him. I served on the investigative committee that investigated him, four of us locked in a room in an undisclosed location for a year. A thousand pages of his stuff.” We're almost inclined to root for Gingrich in the primary just to find out what Pelosi has on him.
