Now he's done it. I'm sure that Bush is shaking in his Texas boots:

"That's why I want to be very clear: If the President takes us to war with Iran without congressional approval, I will call for his impeachment. I am dead serious. ... I'm saying this now to put the administration on notice and hopefully to deter the president from taking unilateral action in the last year of his administration."
