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.

He [Donald Trump] said in the debate - he said, gosh, I'm being audited for two years. Then he said three years. Then he said maybe five years. Listen, if there's a problem in his taxes, the voters have a right to know, because come September, October, the general election, folks in the media are going to make a heyday about any problems in his taxes.

I am long term optimistic and short term pessimistic on immigration. Long term, I'm optimistic because there's a lotta bipartisan agreement outside of Washington on immigration. There's overwhelming bipartisan agreement, number one, that we need to secure the borders. That we need to finally do something to stop illegal immigration.

I believe we should follow the text of every law, even (a) law I disagree with, it's one of the real differences -- if you look at President Obama and the lawlessness, if he disagrees with a law he simply refuses to follow it or claims the authority to unilaterally change.

It is my hope that all of the Republicans who recognize that nominating a candidate who agrees with Hillary Clinton on a host of issues, who has a very similar record, is not the path to victory. And if we come together, if conservatives stand together, we're going to have a great night on Tuesday.

I am perfectly happy to compromise whether it's with Democrats or anybody else, as long as we're reducing the size of government.

I think data is incredibly powerful for understanding what people are thinking and for allocating resources.
