Bush to veto Iraq bill requiring troop withdrawal

Moving toward a veto of a war spending bill, US President George W. Bush said Tuesday that Democrats who made the legislation a showdown over withdrawing US troops could turn Iraq into a "cauldron of chaos" with their approach. "Success in Iraq is critical to the security of free people everywhere," Bush said at the headquarters of US Central Command, which oversees military operations in Iraq and the rest of the Middle East. Congress was expected to send the bill to the president sometime Tuesday, and he planned to veto it either later Tuesday or early Wednesday.
