I'm not poor, but I'm not rich, either.

But here's what I would tell people of my generation. I turn 40 this year. There isn't going to be a Social Security. There isn't going to be a Medicare when you retire. Forget about what your benefit is going to look like. There isn't going to be one if we don't make some reforms to save that program now.

There is one way, only one way to solve it, and that is through legislation. It cannot be through an unconstitutional executive order that violates the Constitution. That is, it doesn't matter here what you think about immigration: here you cannot violate the nation's Constitution, period.

ISIS is the most sophisticated terror threat we have ever faced. We are now at a time when we need more tools, not less tools. And that took we lost, the metadata program, was a valuable tool that we no longer have at our disposal.

Our higher education system is controlled by what amounts to a cartel of existing colleges and universities, which use their power over the accreditation process to block innovative, low-cost competitors from entering the market.

When I'm president of the United States, we're going to have a VA that cares more about our veterans than about the bureaucrats who work at the VA.

I believe we must study which changes must be made now that the immigration system has changed, because we are seeing, I believe, that at this time we are inviting people to come to the U.S. on very dangerous trips.
