One of the things that I have encouraged President Trump to do, and I'm optimistic about this, is to take on directly the regulatory state; to take it on, to fire bureaucrats.

I was then and am now very much a happy warrior, very much joyful. Not engaging in character attacks myself, just putting out, "Here are the facts, here are the evidence."And I noted, for example, that both of them [Marco Rubio and Donald Trump] were relying on fabrications.

For anyone who doesn't believe that Donald Trump is the best candidate to go head to head with Hillary Clinton in November, and that's about 70 percent of Republicans nationwide who don't think Donald Trump is the right guy, our [President's] campaign is the only campaign that has beaten Donald Trump and that can beat Donald Trump.

America is at war. Our enemy is not violent extremism. It is not some unnamed malevolent force. It is radical Islamic terrorist.

President [Barack] Obama has talked about fundamentally transforming this country. There's 7 billion people across the face of the globe, many of whom want to come to this country. If they come legally, great. But if they come illegally and they get amnesty, that is how we fundamentally change this country, and it really is striking.

We will not defeat radical Islamic terrorists as long as we have a president [Barack Obama] unwilling to utter the words 'radical Islamic terrorists'.

The American free market system is the greatest engine for prosperity and opportunity that the world has ever seen. Freedom works.
