War and Piece
The WaPo's Al Kamen reports that Wolfowitz is leaving too:

There was buzz early in the week that Defense Secretary Donald H. Rumsfeld and Deputy Defense Secretary Paul D. Wolfowitz had seen President Bush and informed him that Wolfowitz would be leaving and that Rummy wanted a big-time corporate type to be the new deputy.

We quickly rounded up the usual suspects to see if this was true, but they only said things like: "There may be something there," or, "You'll just have to be patient," or, when asked who might know, suggested we call Newt Gingrich.
