There should be full engagement to protect our country from a grave threat, which is the weakest foreign policy since Jimmy Carter.

We now have a national security consideration, public health issues, we have an epidemic of heroine overdoses in all places in this country because of the ease of bringing heroine in. We have to secure the border.

I'm a skeptic. I'm not a scientist. I think the science has been politicized.

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.

Work needs to be the single biggest requirements. No more waivers as this administration has done. There should be real work eligibility.

It is a serious undertaking and yes, we do need more fencing and we do need to use technology, and we do need more border control. And we need to have better cooperation by the way with local law enforcement. There are 800,000 cops on the beat, they ought to be trained to be the eyes and ears for law enforcement for the threat against terror as well as for immigration.

That, by the way, is perhaps the most ludicrous comment I've ever heard, that climate change is a bigger threat to our country than radical Islamic terrorism.
