Bush to touch on Iraq, US

WASHINGTON -- President Bush will broadly outline his case for possible war against Iraq in Tuesday night's State of the Union address, leaving it to Secretary of State Colin Powell to come forward later with what the administration says is fresh evidence of Saddam Hussein's ties to Osama bin Laden's terrorist network.\nBush will address the nation at 9 p.m. EST as polls show that Americans are increasingly reluctant to back war with Iraq, particularly without more evidence that Saddam is a threat to the United States.\nPowell said the administration will reveal new evidence "in the days ahead" of Iraq's connections to bin Laden's al Qaeda network. The White House says Iraq has illicit chemical and biological weapons, an assertion denied by Baghdad.\nSenior White House officials said Bush opted for a broad argument against Saddam to avoid having the State of the Union dominated by Iraq.
