WASHINGTON (AP) - President Bush's plan to send more troops to Iraq ran into a wall of criticism on Capitol Hill on Thursday as administration officials drew confrontational, sometimes mocking challenges from both Democrats and Republicans.

Defense Secretary Robert Gates said in response that the administration might abandon the increase
if the Iraqi government doesn't do its part, but he provided no timetable. "I think most of us, in our minds, are thinking of it as a matter of months, not 18 months or two years," he told the House Armed Services Committee.
