The Iranian people are getting restive because of the challenges that sanctions have posed to their economy.

We still have sanctions on Iran for its violations of human rights, for its support of terrorism and for its ballistic missile program. And we will continue to enforce these sanctions vigorously. Iran's recent missile test, for example, was a violation of its international obligations.

The good news is that the Paris Agreement is not just a bilateral agreement between the United States and some other country. You have 200 countries who came together. It's an international agreement.

When you take on the position of president, you are committing yourself to, first and foremost, protecting the American people. You are accepting an institutional role that requires you to make hard decisions and hard choices, and as a consequence you have to take your moral sense and not put it aside.

My top priority in any trade negotiation is expanding opportunity for hardworking Americans. It's no secret that past trade deals haven't always lived up to their promise, and that's why I will only sign my name to an agreement that helps ordinary Americans get ahead, the bill put forward today would help us write those rules in a way that avoids the mistakes from our past, seizes opportunities for our future and stays true to our values.

This is the defining issue of our time. This is a make-or-break moment for the middle class and for all those who are fighting to get into the middle class.
