I don't think the science is clear of what percentage is man-made and what percentage is natural. It's convoluted, for the people to say the science is decided on this is really arrogant, to be honest with you.

I'd be wary of simple solutions to complex problems.

I think people have good ideas on this. Clearly, we need to secure the border. Coming here legally needs to be a lot easier than coming here illegally.

If more people were actively engaged in advocating their positions I think we'd have a better society.

We need to engage with the Arab world.It is not a serious proposal to say that - to the people that you're asking for their support that they can't even come to the country to even engage in a dialogue with us.

America still is an exceptional country. We love to lead and we love to win. And we do it, when we take on any challenge and when we take - we support our friends.

If we want to destroy ISIS,if we expect to do this on our own, we will fail but if we do it in unison with people who are also are at risk and threatened by Islamic Radical terrorism, we'll be far more successful.
