Glad to know our president values the opinions of congress:

"President George Bush formally asked Congress yesterday for almost $75bn (£48bn) to fund the war. He had delayed making the request until the invasion got under way, for fear of objections."

I wonder how much of the Bush administrations behavior comes from their attempt to reverse the "weakening" of the executive branch over the past however many years as a result of Nixon and Clinton. There were certainly a lot of early comments made by the administration implying this was one of their big goals.
