[Marco Rubio] you're a lousy businessman.

I think [Iranian deal] was the worst deal I've ever seen negotiated. The deal that was made by the [Barack] Obama administration. I think it's a shame that we've had a deal like that and that we had to sign a deal like that and there was no reason to do it and if you're going to do it, have a good deal.

I think NATO is obsolete. NATO was done at a time you had the Soviet Union, which was obviously larger - much larger than Russia is today. I'm not saying Russia is not a threat. But we have other threats. We have the threat of terrorism. And NATO doesn't discuss terrorism. NATO's not meant for terrorism. NATO doesn't have the right countries in it for terrorism.

And with technology, as we know, it can go very, very rapidly.

I agree, and a lot of people even within my own party want to give certain rights to people on watch lists and no- fly lists.

This will be one of my most important elements. When I talk cost cutting, I do for so many different departments where the money is pouring and they don't even know what to do with it. But when it comes to the military we have to enhance our military. It's depleted. That's the word I tend to use.

The best thing I've done? Well, I've created four beautiful children.
