We`re seeing something fairly remarkable happen on the political train. We`re seeing the Washington establishment abandoning Marco Rubio. I think they`ve made the determination that Marco can`t win. And they`re rushing to support Donald Trump.

We need to do whatever is necessary to utterly defeat ISIS....We're not using our overwhelming air power. We're not arming the Kurds. Those need to be the first steps. And then we need to put whatever ground power is needed to carry it out.

I'll tell you whose view on [Bashar] Assad is the same as mine. It's Prime Minister [Benjamin] Netanyahu. Prime Minister Netanyahu has said Israel doesn't have a dog in that fight because Assad is a puppet of Iran, a Shia radical Islamic terrorist, but at the same time, Prime Minister Netanyahu doesn't want to see Syria governed by ISIS.

Marco Rubio was fighting to grant amnesty and not to secure the border, I was fighting to secure the border. And this also goes to trust, listening on to campaign trails. Candidates all the time make promises. You know, Marco said," he learned that the American people didn't trust the federal government."

There is no moral absolute, and this leads us to situational ethics, which unfortunately is being taught in public schools all over America. This means that right and wrong is dependent upon the circumstances.

It's not beneficial when you have a presidential candidate like Donald Trump, telling his supporters "punch that guy in the face." I think everyone candidate ought to aspire toward civility, towards decency, towards bringing us together. I don't think we should be using angry and hateful rhetoric.

Popularity isn't the end-all, be-all. What matters far more is that you stick to your principles, that you stand up and you live a life of integrity.
