What is portrayed as high-minded positions on issues sometimes is just designed to carve out some of their commercial interests.

Sanctions alone could not stop Iran's nuclear program. But they did help bring Iran to the negotiating table.

All Americans should be deeply troubled by the fatal shootings of Alton Sterling in Baton Rouge, Louisiana and Philando Castile in Falcon Heights, Minnesota. We've seen such tragedies far too many times, and our hearts go out to the families and communities who've suffered such a painful loss.

We have to ensure free and open exchange of information. That starts with an open internet. I will take a backseat to no one in my commitment to network neutrality. Because once providers start to privilege some applications or websites over others then the smaller voices get squeezed out and we all lose. The internet is perhaps the most open network in history, and we have to keep it that way.

It is my judgment that had I spent the first two years trying to get a single-payer system, all those folks who now have health insurance that didn't have it would still be uninsured. And those are millions of people whose lives are impacted right now.

Without a deal [with Iran], the international sanctions regime will unravel with little ability to reimpose them. With this deal, we have the possibility of peacefully resolving a major threat to regional and international security.
