I haven't officially spoken in public about that issue, but I don't think it's a secret that Carlos [López-Cantera] has been a good friend of mine for many years. I respect him. I think he has done a great job as a state representative, as property appraiser in South Florida, and he's doing so now as lieutenant governor of Florida, and I think he would be a great senator, but I don't have an announcement for you today.

I believe that the bigger problem is that we're seeing people who arrive from Cuba and a year and a day later are travelling to Cuba 40 times a year, they're staying, and that's hard to justify. The problem is not that I want to deny anything to anyone; it is the need to justify those laws.

I think what we need to do is understand our number one obligation is to act in the national interest of the United States of America.

And here's the fact: the fact is it doesn't solve the problem. First of all, if you taxed these people at 100 percent, basically next year you said, 'Look, every penny you make next year the government's going to take it from you,' it still doesn't solve the debt.

Immigration is not an issue that I read about in the newspaper or watch a documentary on PBS or CNN. It's an issues I've lived around my whole life. My family are immigrants. My wife's family are immigrants. All of my neighbors are immigrants.
