McCain, from a White House ceremony about the Iraq resolution in 2002:
The Constitution of the United States designates the President of the United States as Commander-in-Chief. The Congress of the United States plays a role, and I believe that this process we are about to embark on is the appropriate role that Congress should carry out its responsibilities. But at the end of the day, the final, most serious responsibility of sending young American men and women into harm's way rests with the President of the United States.
My Constitution says that responsibility rests with Congress. The president decides who gets sent where. Congress decides to do the sending.
