It is possible, I supposed, to imagine an extraordinary circumstance in which it would be necessary and appropriate under the Constitution and applicable laws of the United States for the President to authorize the military to use lethal force within the territory of the United States.

The Constitution guarantees due process, not judicial process.

You constantly hear about voter fraud... but you don't see huge amounts of vote fraud out there.

Any decision to use lethal force against a United States citizen - even one intent on murdering Americans and who has become an operational leader of al-Qaida in a foreign land - is among the gravest that government leaders can face.

Whether it is an attempt to bomb the New York City subway system, an attempt to bring down an airplane over Detroit, an attempt to set off a bomb in Times Square ... I think that gives us a sense of the breadth of the challenges that we face, and the kinds of things that our enemy is trying to do.

There are a whole variety of reasons I want to be attorney general, a whole variety of things that I do as attorney general that go beyond national security.

I think that people, despite my law enforcement background, view me as taking these consistently progressive stands, and I think that, philosophically, there is a desire to get at that person. But I think the stands I have taken are totally consistent with a person who is looking at things realistically, factually.
