So, we've got two "senior administration officials" (Novak)/"top White House officials"(Washington Post) leaking the identity of undercover CIA agents. Any guesses who they might be?

The first almost has to be Fleischer. It's hard to see two top White House officials talking to multiple members of the press without having the administration's top press official involved.

Wilson pointed the finger at Rove. Could it be that simple? Ari and Karl?
