What I do know is that drones are a modern weapon. When used effectively, when taking out ISIS or terrorist leaders, that's pretty impressive. When bombing wedding parties of innocent people and killing dozens of them, that is, needless to say, not effective and enormously counterproductive. So whatever the mechanism, whoever is in control of that policy, it has to be refined so that we are killing the people we want to kill and not innocent collateral damage.

The focus, to my mind, is to make sure that Donald Trump does not become president of the United States. I think by temperament he is unqualified to be president. I think his views - you have a guy who's running for president who rejects science, doesn't even believe climate change is real, let alone wants to do something about it, wants to give hundreds of billions of dollars in tax breaks to the top two-tenths of one percent.

We are spending hundreds of billions of dollars maintaining 5,000 nuclear weapons. I think we need major reform in the military, making it more cost effective, but also focusing on the real crisis that faces America.

I will tell you is the antidote to [Donald] Trump is a very strong progressive agenda that says, yes, I know you`re angry. And you know what? You should be angry because you`re working longer hours for low wages. You have a right to be bitter and you have a right to be that.

I worry very, very much about an isolated country. That's what makes me nervous. Russia lives in the world. China lives in the world. North Korea is a very, very strange country because it is so isolated, and I do feel that a nation with nuclear weapons, they have got to be dealt with. Dealt with effectively.

The Federal Reserve needs to provide small businesses in America with the same low-interest loans it gave to foreign banks.

I'm running for president, because as I go around this nation, I talk to a lot of people. And what I hear is people's concern that the economy we have is a rigged economy.
