Let's be clear about what this [presidential] campaign is about. It's not about Donald Trump, he's an entertaining guys, he's the greatest show on Earth.

[Donald Trump twitts] "Lightweight Marco Rubio was working hard last night." This is true. "The problem is he's chalker and once a chalker, always a choker," I guess that's what he meant to say. He spelled choker, c-h-o-k-e-r.

Leaders at the highest levels of our government are undertaking a deliberate and systematic effort to redefine our government, our economy and our country.

I'm all for reforming our higher education system, in the 21st century, to have the skills you need for a middle-class job, you need higher education of some form or fashion.

I think strong rhetoric and strong action are two separate things. Anyone can use tough words. Anyone can go over the top and say things that sound strong. But sounding strong is not enough. You have to know exactly how you're going to do it. And if you look at some of the policies he's talked about, they would not make America stronger.
