PORTSMOUTH, N.H. — Presumptive Republican presidential nominee Mitt Romney says "of course" he would have ordered Osama bin Laden killed.

President Barack Obama's re-election campaign has raised questions about Romney's willingness to assassinate the former terrorist leader. Obama authorized the U.S. military raid in Pakistan that ended with bin Laden's death one year ago this week.

Speaking to reporters in New Hampshire on Monday, Romney said he would have made the same decision. He says "even Jimmy Carter would have given that order."
