Let us agree here today to adopt among ourselves a simple and unwritten rule. We will not rise to criticize someone else's idea unless we are prepared to offer an alternative idea of our own.

Let me start by saying that I do not enjoy nor relish the partisan role of attack dog. I never found any fun in that. I don't think it's constructive. I don't intend to become that here in the Senate.

Donald Trump is a world-class con artist. He conned all these people that signed up for Trump University. Now he's trying to do the same thing to Republican voters. He's trying to convince them that somehow he's the guy that is going to stand up to illegal immigration, but he hires illegal immigrants, that he's fighting for American workers, but he's hiring foreign workers for his hotels, that he's going to bring back jobs from China and from Mexico, but, in fact, he's creating jobs in China and Mexico, because that's where all of his suits and ties that he sells are made.

I mean, on virtually every major issue before this country that is the natural purview of the federal government, it's important to have some specificity about what you're going to do if you want to be the president. And so I agree that, up until this point, it hasn't been a huge factor.

We will be in this race as long as it takes. We're going to be in as many states as it takes to ensure that I'm the nominee and that Donald Trump never gets to 1,236 delegates, which is what he needs to be the nominee.

For over 200 years this has been a special country. A unique place where anyone from anywhere can achieve anything. But now millions of Americans feel like they're being left behind. Insecure in their future and unsafe in the face of terrorism.

Barack Obama hasn't kept us safe. The problem is we had an attack in San Bernardino. And we were paying attention to the most important issue we have faced in a decade since 9/11, and then all the talk was about this proposal, which isn't going to happen.
