The kind of plan that Donald [Tramp] has put forth would be trickle-down economics all over again. In fact, it would be the most extreme version, the biggest tax cuts for the top percent of the people in this country than we've ever had.

I believe that I have created a lot of cognitive dissonance in the minds of people who are comfortable with stereotypes.

I think what President [Barack] Obama has done is to chart a steady course. When I was there, the first four years we had a lot of cleanup to do. We inherited a lot of bad feelings from the [George W.] Bush administration, and much of what I spent my time doing was traveling around the world reassuring friends and allies.

With prior Republican nominees for president, I disagreed with them on politics, policies, principles, but I never questioned their fitness to serve. Donald Trump is different.

What I want to do is make sure middle class kids, not Donald Trump's kids, get to be able to afford college.

No human being is immune to adversity or personal setbacks.

I mean, I'm a big believer in talking to people when you can and trying to solve problems when you can.
