I have a comprehensive energy policy, but it really does include fighting climate change, because I think that is a serious problem.

For more than a half a century, we know that we prospered because of a bipartisan consensus on defense and foreign policy. We must do more than return to that sensible, cooperative approach.

Well, I'm just quoting you when you [Donald Trump] were asked about a potential nuclear competition in Asia, you said, you know, go ahead, enjoy yourselves, folks.

We need fair rules of the road, so big corporations can't use their power to gain unfair advantages.

If we repeal [ Barack Obama's health care law] as Donald [Trump] has proposed, all of those benefits I have mentioned are lost to everybody...and then we will have to start all over again.

When you inherit the level of economic catastrophe that President Obama inherited, it was a real touch-and-go situation.

I believe that it is imperative that we learn from the mistakes.
