The problem we have is not Democrats versus Republicans. It is a Washington cartel. I've said many times the biggest divide we have politically is not between Republicans and Democrats. It's between career politicians in both parties and the American people.

One of the problems in Washington is there are far too many politicians who desperately just want to get re-elected.

I think if you're at home and you don't want Donald Trump to be the Republican nominee, then the only candidate who can beat Donald is our campaign. And so I would encourage, even if you like another candidate, stand with us if you don't want Donald to be the nominee.

We need a much better understanding of the climate before making policy choices that would impose substantial economic costs on our Nation.

ISIS and radical Islamic terrorism will face no more determined foe than I will be.

I had a back-and-forth where I asked Donald Trump, is it true or false that he said the government should pay for everyone's health care? He said it's false. Listen, within minutes, we put out a video just contrasting what he said there with video of him just a few months earlier saying exactly the opposite.

I do believe, in the long term, we will either get back to the principles that built America or we lose this country. And I'm an optimist.
