As long as I sit at Henry Clay's desk, I will remember his lifelong desire to forge agreement, but I will also keep close to my heart the principled stand of his cousin, Cassius Clay, who refused to forsake the life of any human, simply to find agreement.

Currently, the United States has troops in dozens of countries and is actively fighting in Iraq, Syria, Libya, and Yemen (with the occasional drone strike in Pakistan). In addition, the United States is pledged to defend 28 countries in NATO. It is unwise to expand the monetary and military obligations of the United States given the burden of our $20 trillion debt.

You shouldn't have one opinion when you're running and another when you're president.

The other thing to realize is that almost all these shootings, including this shooting [in San-Bernardino], happened in a government building where people are not allowed to defend themselves. While it's not the ultimate answer, the ultimate answer would be no violence, part of the answer is saying, "We need to allow people to defend themselves."

We have to have a more realistic foreign policy and not a utopian one where we say, oh, we're going to spread freedom and democracy, and everybody in the Middle East is going to love us. They are not going to love us.

These attacks prove one thing for certain: the liberal establishment is desperate to keep leaders like me out of office, and we are sure to hear more wild, dishonest smears during this campaign.

I don't think I'm really open to having Washington change me.
