This bill to withdraw U.S. troops and Defense Department contractors from Iraq (H.R. 2237) was purely a symbolic bill with little chance of passage by the House. The bill would require the withdrawal of troops and contractors to begin within 90 days of the bill's enactment, and to be completed within 180 days from the beginning date of the withdrawal.
According to Article I, Section 8 of the Constitution, only Congress can declare war, and consequently our soldiers are not fighting under a constitutional mandate.
