Members of Congress debate Iraq policy as the White House plans an increase of 21,000 U.S. troops in Iraq. U.S. lawmakers squared off on Tuesday over President George W. Bush's troop buildup in Iraq, with Democrats declaring Americans had lost faith in the war and Republicans warning against undermining the U.S. struggle with terrorism. Democrats in the House of Representatives began three days of debate on a two-sentence resolution opposing Bush's decision to sent 21,500 more combat troops to Iraq. The measure would not force the president to change course, but would be the first time lawmakers have challenged him directly on the war.
