Sen. John McCain renewed efforts to end the CIA's control over U.S. drone strikes after an attack on an al-Qaida compound in Pakistan killed two hostages.

Now that drones have become "an integral part" of U.S. military operations, it makes sense for such airstrikes to be managed by the nation's armed services rather than by spy agencies, the Arizona Republican said Sunday on CNN's "State of the Union" program.

McCain, chairman of the Senate Armed Services Committee, acknowledged his bias in seeking to give the Defense Department greater control, adding that the military has "the capabilities and the equipment" that the Central Intelligence Agency lacks to conduct effective drone strikes.
