What's going on in the Senate is kind of a politics of escalation. We're getting sort of like the Mideast: pay back everybody when you're in charge.

We don't have enough American troops inside of Iraq to destroy ISIL any time soon.

Iran is part of the problem, not the solution. And the Russian government is ignoring reality.

My advice is if we can't replace Obamacare by ourselves, to go to the Democrats and say this. 10% of the sick people in this country drive 90 percent of the cost for all of us. Let's take those 10 percent of really sick people, put them in a federal managed care system so they'll get better outcomes, and save the private sector market if we can't do this by ourselves. That's a good place to start.

I would love to have a good deal to end the nuclear ambitions of the Iranians, but I don't trust the Iranians. They've been lying and cheating.

I think the best thing, if you can't get an air-tight deal with every "I" dotted and every "t" crossed is let the next president have a chance to deal with the Iranians.

When it comes to immigration reform, now is the time ... I've never seen a better political environment ... I'm not doing immigration reform to solve the Republican Party's political problem. I'm trying to save our nation from, I think, a shortage of labor and a catastrophic broken system.
