I think there are a number of issues that we should be addressing. I have put forth a plan to defeat ISIS.

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.

I believe in raising the minimum wage and equal pay for work.

I think if you had a capital-gains system where the long, patient capital would actually be rewarded, nanosecond capital turning would not be.

I have many, many old friends, and I always think that it`s important, when you get into politics, to have friends you had before you were in politics and to understand what`s on their minds.

Independent experts have looked at what I've proposed and looked at what Donald's [Trump] proposed, and basically they've said this, that if his tax plan, which would blow up the debt by over $5 trillion and would in some instances disadvantage middle-class families compared to the wealthy, were to go into effect, we would lose 3.5 million jobs and maybe have another recession.

I think we need to do much more with our tech companies to prevent ISIS and their operatives from being able to use the Internet to radicalize, even direct people in America and Europe and elsewhere.
