I think we should be very clear on this. You know, this country was founded on the principles of the Enlightenment... It was the idea that people could talk, reason, have dialogue, discuss the issues. It wasn't founded on the idea that someone would get struck by a divine inspiration and know everything right from wrong. I mean, people who founded this country had religion, they had strong beliefs, but they believed in reason, in dialogue, in civil discourse. We can't lose that in this country. We've got to get it back.

I tremendously admire, and I think we all should, the great work done by our commander in chief, our president George Bush...

It 's really hard to impose democracy. It has to emerge naturally. You have to get out of the way and let it happen.

Once you take yourself off the pedestal, saying, "It's bad for you to torture, but for us, this is our national security, so we're gonna do it". You can't live that way and the United States doesn't need to do it, it shouldn't do it, and I think a Democratic administration, whoever the democratic president is, will repudiate that kind of conduct. I think it was an overreaction caused by a lot of different strains of thought in the administration. I think it was clearly wrong and I think that repudiation, which will come from the United States, will be a key in restoring America's legitimacy.

We've never finished the investigation of 9/11 and whether the administration actually misused the intel information it had. The evidence seems pretty clear to me. I've seen that for a long time.

Global warming is a matter of national security. Will we live in a world where we must fight our neighbors for fresh water and food? Or will we take the lead now and leave to our children and grandchildren a world better off than the one we inherited from our parents?

Well, it came from the White House, it came from people around the White House. It came from all over. I got a call on 9/11. I was on CNN, and I got a call at my home saying, 'You got to say this is connected. This is state-sponsored terrorism. This has to be connected to Saddam Hussein.
