Confronting climate change is, in the long run, one of the greatest challenges that we face, and you can see this duty or responsibility laid down in scriptures, clearly.

At every step of the way, George W. Bush has put the narrow interests of the few ahead of the interests of most Americans.

Jesus did not help just the sick who could afford to pay for it.

The agreement is fundamentally that we want to try to resolve this. The agreement is that ISIL is a threat to everybody, and we need to come together to find a way to fight ISIL. The agreement is that we want to save Syria, keep it unified, keep it secular. So surely in those very fundamental principles on which we could agree.

We need a leader who has a sense of balance, an understanding of the ebb and flow of history and a sense of our country's unique place in it. This is a foreign policy debate, and you cannot conduct foreign policy without a sense of what we are fighting for. And any President who can reduce the conduct of this country's affairs to a morning's attack by a bunch of demented fascists does not, in my view, understand what this great nation is all about.

We achieved a deal with the Russians that didn't wind up in two days of strikes that would have sent a, quote, "message," but would not have removed the weapons. We struck a deal to get all of the declared weapons out of Syria. Never before in a conflict has that ever happened, that during the conflict weapons of mass destruction are taken out of the zone of conflict. And thank God we did that, because if we hadn't done that, today ISIL would have those chemical weapons in large parts of the country.

I think that for many of us, the years of the Civil Rights movements - Martin Luther King, Bobby Kennedy running for president in 1968 to end the war and so forth - these were defining moment in terms of trying to hold government accountable and have a level of responsibility and truth-telling.
