McCain versus Rumsfeld versus Bush
John McCain has told AP that he has "no confidence" in Secretary of State Rumsfeld, but that the President "can have the team that he wants around him." Thus McCain said that if Rumsfeld is not fired, he has "no confidence" in the President.
McCain wants more troops in Iraq.
McCain, of course, was mentioned as a possible Sec Def before the President announced that Rumsfeld was staying.
