I think a deal has been done here. Armitage is in the Powell camp. If he is going to be the fall guy, something stinks.
The Armitage leak was not directly a part of the White House's fierce anti-Wilson crusade. But as Hubris notes, it was, in a way, linked to the White House effort, for Amitage had been sent a key memo about Wilson's trip that referred to his wife and her CIA connection, and this memo had been written, according to special counsel Patrick Fitzgerald, at the request of I. Lewis Scooter Libby, the vice president's chief of staff. Libby had asked for the memo because he was looking to protect his boss from the mounting criticism that Bush and Cheney had misrepresented the WMD intelligence to garner public support for the invasion of Iraq.
