I can tell you what I believe, particularly about Mexican-Americans: they are a community that has contributed greatly to this country, they work extremely hard, they've been very productive citizens of our country, and I think that's true of many ethnic groups in this country.

We have a violence problem in America. And no one is having a debate about the violence problem. And I think this is a missed opportunity to have an honest and open conversation in this country about why these horrifying things are happening, not simply what they're using to carry this out, but why are people doing this to begin with?

I'm going to be working the next 25 or 30 years. People like me, if we want, number one, for no benefit reductions for our parents and our grandparents, number two, for the system to survive and exist for us, and, more importantly, number three, for the system to exist for us children, we are going to have to make reforms to that system.

My preference is that we beat him [Donald Trump] outright in the primary process. And I believe that's exactly what's going to happen here in the next few weeks, especially as we move to winner-take-all states. The terrain begins to change.

Moammar Gadhafi and the revolt against Gadhafi was not started by the United States. It was started by the Libyan people. And the reason why I argued we needed to get involved is because he was going to go one way or the other. And my argument then was proven true, and that is, the longer that civil war took, the more militias would be formed and the more unstable the country would be after the fact.

Government should allow people to go out and do the things Americans have always done, create jobs and prosperity. And America's role in the world - the world is a safer and better place when America is the strongest country in the world.

A president cannot make decision on what someone might know in the future.
