U.S. President George W. Bush is pushing Congress to provide more money for combat and reconstruction in Iraq and Afghanistan - funds the Pentagon says it needs by the first week of May. "I applaud the House and Senate for their strong support of my supplemental funding request for our troops serving on the front lines," Bush said Saturday in his radio address. "This funding will help provide the weapons, ammunition, spare parts and equipment that our troops need to do their job," he said. "I urge Congress to come together to resolve their remaining differences, and send me a bill quickly." House and Senate negotiators are expected to act soon to sort out differences between their versions of the $81 billion spending bill. Both versions would push the total cost of combat and reconstruction past $300 billion since the attacks of Sept. 11, 2001.
