Donald Trump says he knows more about ISIS than the generals. No, he doesn't.

I wanted to work on policy because I think it really makes a difference.

When you guys go into some kind of a deal, you know, are you going to do that development or not, are you going to do that renovation or not, you know, you look at the numbers. You try to figure out what's going to work and what's not going to work.

I think we've got to look at corporate law. Back in the day when I studied it, there were different constituencies that were to be served, and I think there was a real wrong turn about 20 to 25 years ago when the theory began to be promoted that your highest duty - in fact, some would argue, your only duty - is to maximize shareholder return. I just don't buy it. And it wasn't the original underpinnings of the legal theory of corporate law.

I believe we should have a full-court press diplomatic effort. If Trump doesn't want to listen to the experts inside his own government, then go to people outside in think tanks and academia who know about this very complicated region, and particularly North Korea.

I think the stress on income inequality is something that every American should take seriously, we have got to figure out how we're going to provide more economic opportunity - good jobs with rising incomes - and I'm excited to work with Senator Sanders in doing that.

Countries that will not tax their elite who expect us to come in and help them serve their people are just not going to get the kind of help from us that historically they may have.
