Facing a Republican revolt in the Senate, President George W. Bush urged Congress on Friday to join in backing legislation to spell out strategies for interrogating and trying terror suspects, saying "the enemy wants to attack us again." "Time is running out," Bush said in a Rose Garden news conference. "Congress needs to act wisely and promptly." Bush denied that the United States might lose the high ground in the eyes of world opinion, as former Secretary of State Colin Powell suggested. "It's unacceptable to think there's any kind of comparison between the behavior of the United States of America and the action of Islamic extremists who kill innocent women and children to achieve an objective," said Bush, growing animated as he spoke.
