Bush pressured for Iraq exit strategy

As politicians in Washington poke President Bush about an exit strategy for Iraq, Baghdad suffered four bomb attacks on April 18, 2007, that killed 183 people. It was the bloodiest day since the U.S. troop increase began nine weeks ago.

President Bush maintains he will veto a bill that has a time table for troop withdrawal. Still, Democrats said they will soon send the president a bill that includes a pullout date.
