WASHINGTON -President Bush, facing opposition from both parties over his plan to send more troops to Iraq, said he has the authority to act no matter what Congress wants.

"I fully understand they could try to stop me from doing it. But I've made my decision. And we're going forward," Bush told CBS' "60 Minutes" in an interview to air Sunday night.

Vice President Dick Cheney asserted that lawmakers' criticism will not influence Bush's plans and he dismissed any effort to "run a war by committee."

"The president is the commander in chief. He's the one who has to make these tough decisions," Cheney said.

The defiant White House stance comes as both the House and Senate, now controlled by Democrats, prepare to vote on resolutions that oppose additional U.S. troops in Iraq. Cheney said those nonbinding votes would not affect Bush's ability to carry out his policies.
