Okay, so here's how it started:

A tipster heard that the Washington Post's Susan Glasser, Bill Hamilton and one more big time Postie were spotted having coffee recently with NYTimes investigative reporter Marilyn Thompson.

Speculation has it that Thompson was upset that the Times didn't run their story about the relationship between Sen. John McCain and a D.C. lobbyist.

Oh, and didn't an investigative gig just open up at the Post recently?

So it should come as no surprise that...Marilyn Thompson is returning to the Washington Post, where she will be the new "Washington accountability editor" on the National desk. She previously worked at the WaPo from 1990 to 2004 before leaving for the Lexington Herald, then the L.A. Times, then the NYTimes.
