U.S. Senator Martin Heinrich (D-N.M.), a member of the Senate Select Committee on Intelligence, issued the following statement on the agreement reached on Iran's nuclear program:
"The agreement reached today is a positive first step to limit Iran's nuclear program. The United States, United Kingdom, Germany, France, Russia, China, and the European Union have all worked to negotiate strict oversight, enforcement mechanisms, and daily inspections that are critical to overseeing this agreement.
"While I welcome this important first step, I realize that challenges lie ahead. In the coming months Iran must show that it is sincere and that it will abide by the commitments it made to the international community. Should it violate the terms of the agreement, I stand ready to support additional sanctions in Congress. I have long supported tough sanctions in hopes of bringing Iran to the table to reach a diplomatic solution, and I am pleased to know they have helped create the conditions for today's agreement and perhaps a more comprehensive deal."
