I'm not going to impugn anyone's integrity. I'm not going to attack their character. And, in fact, I will happily praise both Donald Trump and Marco Rubio as men who I admire, as people who I'm not going to go personal with them.

We need to use overwhelming air power. We need to be arming the Kurds. We need to be fighting and killing ISIS where they are.

Donald [Trump] is a charming person. He can be fun. He can make you laugh. But he can turn on you. And get nasty and personal and vicious.

We don't have a system that knocks on doors of every person in America.

The grass roots are energized because the absolutely highest priority in the country in November is to defeat Barack Obama. I have spoken with literally thousands and thousands of tea-party activists - I have yet to meet a single tea-party leader that is not going to vote for Mitt Romney.

I appreciate the good work that senators in both parties have put into trying to fix our broken immigration system. There are some good elements in this proposal, especially increasing the resources and manpower to secure our border and also improving and streamlining legal immigration. However, I have deep concerns with the proposed path to citizenship. To allow those who came here illegally to be placed on such a path is both inconsistent with rule of law and profoundly unfair to the millions of legal immigrants who waited years, if not decades, to come to America legally.
