WASHINGTON (AP) – A historic veto showdown assured, Democratic leaders agreed Monday on legislation that requires the first U.S. combat troops to be withdrawn from Iraq by Oct. 1 with a goal of a complete pullout six months later. “No more will Congress turn a blind eye to the Bush administration’s incompetence and dishonesty,” Senate Majority Leader Harry Reid said in a speech in which he accused the president of living in a state of denial about events in Iraq more than four years after the U.S.-led invasion.
