Certainly. This is well known, by the way. I haven't heard of anyone contending it. If they do, it would only in an attempt to rewrite history.
Is it 'War'? (ABC News, Sept 13)
I could post more links for you, but it would be easier if you just did a google search for "Rep Bob Barr + declaration of war".
Seems to more than answer your question: additionally, the 9/14 Resolution also gives the President power. Another excerpt that might lend credence to the conspiracy-theorists:
Rep. Bob Barr, R-Ga., today introduced a formal declaration of war against all international terrorists and their sponsors.
No indication is given the President "killed" that introduction. Indeed, if the Congress wanted to pass it, they could have. No indication has been made that Bob Barr himself opposed the final action. He, in fact, voted for the Resolution.
The fact is, there is no Constitutional instruction regarding the manner in which War is Declared: only that Congress has that power. Search the document high and low, you won't find a prescription for the declaration of war.
