President may order killing of American terrorists, Holder says

The attorney general offers a rationale for how the airstrike that killed U.S. citizen Anwar Awlaki in Yemen last year is in line with the Constitution.

The president has legal authority to target and kill American citizens working with Al Qaeda and its allies overseas, according to Atty. Gen. Eric H. Holder Jr., who declared that when such people pose a threat to the country and cannot be captured, "we must take steps to stop them."
