Here’s an indication from Mike Allen at Time:
One move that could buy the President good will with the Hill and the public would be the departure of Defense Secretary Donald Rumsfeld, and many people close to Bush hope that happens sooner rather than later. “He has screwed the President,” said a loyal member of the Bush team who rarely speaks so bluntly. The President said when asked last week that Rumsfeld would serve the rest of the term, but officials say Bush really could not have said anything else, and that is in no way a guarantee that Rumsfeld will still be running the Pentagon at noon on Jan. 20, 2009, when Bush’s successor takes office.
