President Bush Defends Sept. 11 Focus

President Bush dismissed calls that he pull political ads that use images of the devastated World Trade Center to show him as a strong leader in troubled times:

"I will continue to speak about the effects of 9/11 on our country and my presidency," Bush told reporters at a joint news conference with Mexican President Vicente Fox at Bush's Crawford, Texas ranch. "How this administration handled that day as well as the war on terror is worthy of discussion and I look forward to discussing that with the American people."
