"I would not have [the drone program] in the CIA. I would have it located in the Pentagon. They're not the target experts. The experts in targeting is the Pentagon, the Air Force. The CIA's supposed to give us the intelligence to figure out whether the targeting makes sense... The expertise behind them is so absolutely critical. I'd use CIA intelligence and I'd be extremely careful when I used it."

"Today, we are here not to condemn the use of drones in a general sense. Drone technology certainly has its merits and has been useful against our enemies. But the potential for the misuse of drones, or lack of foresight in using them as a general policy—at home or even on the battlefield against terror suspects—raises important constitutional and national security concerns.

We now know that the President has a kill list, which has already included American citizens, such as terror suspect Anwar al-Awlaki. But even overseas, even traitors deserve some due process if they are American citizens, particularly if they are not actively involved in combat. If he was actively engaged in combat against our soldiers, there would’ve been no question—you take him out...

This is not to say that drones should never be used, and they have been used sometimes to good effect. But some in the military community have argued that our current drone program actually makes the nation less safe and undermines our national security...

On the battlefield drones are unquestionably an important tool when Congress has authorized the action. But they are a unique tool. They are a tool that enables the Executive to stretch the limits of Congress' authorization of force.

That is even more true when targeting American citizens, and drone assassinations should not be used in lieu of due process. The Constitution already provides a guide for dealing with citizens suspected of collaborating with radical terrorists—try them for treason."

"I think the American drone program is an important program, which I’m supportive of if used appropriately...

My biggest problem with the drone program is we no longer interrogate terrorists. Right now we’re not getting any information from terrorists because the first option is to kill them."

"[W]hat you can argue is that there are times and places where drone attacks have been effective, there are times and places where they have been absolutely counter effective and have caused more problems when they have solved. When you kill innocent people, what the end result is that people in the region become anti-American who otherwise would not have been.

So, I think we have to use drones very, very selectively and effectively. That has not always been the case."
