I think that Joe Biden is qualified in many respects. But I do point out that he's been wrong on many foreign policy and national security issues, which is supposed to be his strength.

I think we need to address greenhouse gas emissions. But I try to get involved in issues where I see a legislative result... So I just leave the issue alone because I don't see a way through it, and there are certain fundamentals, for example nuke power, that people on the left will never agree with me on. So why should I waste my time when I know the people on the left are going to reject nuclear power?

What was fascinating to me, is that she [Hillary Clinton] still cannot answer eloquently, answers about her e-mails, she still can't explains to me why she's not a third term of [Barack] Obama.

I want to tell the vice president and everybody else that when I'm president there will be a controlling legal authority.

The president(Obama) comparing him to a kid in the back of a classroom, I think, is very indicative of the president's lack of appreciation of who Vladimir Putin is. He's an old KGB colonel that has no illusions about our relationship, does not care about a relationship with the United States, continues to oppress his people, continues to act in an autocratic fashion.

[Hillary Clinton] was saying, "We never going to do anything in Iraq, we're not going to do anything in Syria." Enemies, do whatever you want. Continue the largest humanitarian crisis, 7 million people displaced refugees. Do all this. We're not going to do anything. That is the type of stuff that is been happening for the past 7 1/2 years under President [Barack] Obama.

My greatest fear is the Iranians acquire a nuclear weapon and give it to a terrorist organization. And there is a real threat of them doing that.
