How did congress pay for Iraq War?

This is how they used to pay for the military being in Iraq. October 2003

Bart Stupak, D-Michigan 1st District 10:12:41 AM (00:12:38) 1 minute Mr. STUPAK.
Mr. Speaker, today the House of Representatives is expected to vote on the President's $87 billion supplemental appropriations bill for Iraq.

This $87 billion is on top of the $79 billion we approved last spring.

This is not an easy vote, and I appreciate hearing from my constituents on this issue.

I have no objection to spending every dime necessary to make sure our troops are safe and well-supplied with everything they need to do their jobs, but the $18.6 billion in the bill for civilian reconstruction is simply too big of a handout.

Iraq has vast oil reserves, and we should lend the money to Iraq. The President has refused to separate the military portion of the bill from the reconstruction money.
I will offer an amendment to set aside enough money to pay a $1,500 bonus to every serviceman and woman who served in Iraq and Afghanistan.

Another amendment would require the use of American steel to be used in the rebuilding of Iraqi infrastructure, helping to keep jobs here in America.

Our people at home are hurting for jobs for health care, for quality education, prescription drug coverage. I do not believe we can ask them to continue to sacrifice even more to assume an enormous additional debt for Iraq's civilian reconstruction. That is why I intend to vote against the supplemental appropriation bill.
