It is profoundly troubling when you have Supreme Court justices not following their judicial oath. And taking the role of policy makers and legislators, rather than being judges.

A good impression is great. But a bad impression is even better.

Lets us all have an open conversation about what this might mean if [Donald] Trump gets his way or how we might be able to adjust that and make American people safer.

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

What we saw with both Donald Trump and Marco Rubio, that their response, whenever you point to anything in their record, is just to yell, "Liar, liar, liar," and to get very personal and to make direct character attacks. And my approach, from the very beginning of this President's campaign, starting a year ago in 2015, is that I will not respond in kind. I do not intend to insult any of the candidates.

It is true that I voted against the National Defense Authorization Act, because when I campaigned in Texas I told voters in Texas that I would oppose the federal government having the authority to detain U.S. citizens permanently with no due process. I have repeatedly supported an effort to take that out of that bill, and I honored that campaign commitment.

If I remember correctly, the most efficient campaign in modern times, in terms of burn rate, had been Obama's 2012 reelect, which I believe the number was they spent 37 cents at every dollar.
