This evening on MSNBC's Countdown, host Keith Olbermann cited an "unimpeachable source" who claims that Hillary Clinton Communications Director Howard Wolfson has been looking for a "big money book deal." Radar heard the same whispers at about 4 p.m. today and has been hard at work trying to substantiate the rumors. Here's what we can flesh out beyond Olbermann's gossip:

The rumor says that Wolfson is shopping the "what went wrong" story about the Clinton campaign, and has already approached at least one leading New York agent about the possibility of a deal for the book. It could be true, but it's precisely the sort of nasty rumor Clinton's enemies—or Wolfson's—might float to bury her dying campaign or his reputation.

When contacted by Radar this afternoon, Wolfson responded with a categorical denial of, "Absolutely not. No, no, no, no, no, no. I haven't spoken to any agents, no publishers, nothing." (He made a similar denial to Politico's Ben Smith.) Asked if he met with anyone who could have been mistaken for an agent or publisher, Wolfson said "no." Asked why someone would think such a thing, he replied, "I... don't know," all of which, it should be noted, is exactly what you'd say if you were drawing $200,000 a month to advise a campaign that still shows every appearance of soldiering on despite the staggering odds against success. "It also happens to be true," says Wolfson of his denial. But then he would, wouldn't he?
