Vice president Dick Cheney talked to CBS' Bob Schieffer about the legality of a president's actions during war time. Cheney implied that a president's actions were legal if those actions didn't result in his impeachment.
SCHIEFFER: Do you believe that the president in time of war, that anything he does is legal?
CHENEY: I can't say that anything he does is legal. I think we do and we have historic precedent of taking action that you wouldn't take in peacetime but that you will take sometimes in war time in order to do the basic job that you sign up to when you take the oath of office which is to support and defend the constitution against all enemies foreign and domestic. If you hark back in our history you can look at Abraham Lincoln who suspended the writ of habeas corpus in the middle of the Civil War.
SCHIEFFER: But nobody thinks that was legal.
CHENEY: Well, no. It certainly was in the sense he wasn't impeached.
