I've been very lucky to have had a supportive family, a great education, enormous opportunity and challenge.

What we have done is when the threat has been directed at the United States, i.e., the terrorist threat from ISIL or Al-Qaeda in Syria, is to go after them.

I'm apologetic when I feel like I've made a mistake. And when I have done a disservice to myself or someone else. But I don't feel a need to apologize for doing or saying something that I think needs to be said, just because it may not sit comfortably with somebody else.

I have been to Libya and walked the streets of Benghazi myself.

It is manifestly in the interest of the United States to deal with the very real threat that climate change poses. And that's why President Obama has worked so hard to reduce our own emissions and to lead internationally in forging the Paris climate agreement.

The notion that -- which some people are trying to suggest, that by asking for the identity of an American person, that is the same as leaking it, is completely false. There's no equivalence between so-called unmasking and leaking.

I have great ambitions for when I get out of government. I will watch a broader range of stuff.
