What every American should know is that we have more people in jail today than any other country on Earth, more than China. We have some 2.2 million people in jail. What that means is that a lot of lives are being destroyed.

We can combat climate change effectively. What we are lacking now is not the brain power, not the knowledge, not the technology. What we are lacking is the political will power, and we need your help by the millions to tell Congress to stop worrying about their fossil fuel contributors to their campaigns and worry about their kids and grandchildren.

It is beyond my comprehension why today in America, hundreds of thousands of bright young people are unable to go to college - for one reason: that their family lacks the funding. And together we are going to change that.

The combat [with ISIS] on the ground must be done by Muslim troops with our support. We must not get involved in perpetual warfare in the Middle East.

In my view, one of the major reasons that we have so many people in jail is that we have turned our backs on a lot young people.

I took an oath to support and defend the Constitution of the United States, and I'm concerned that voting for this [anti-terrorism] legislation fundamentally violates that oath.

I am on the Health Education Labor Committee. That committee wrote the Affordable Care Act. The idea I would dismantle health care in America while we're waiting to pass a Medicare for all is just not accurate.
