Congress has to be fully part and parcel of doing this.

I think one of the most powerful things that happened in Iran in recent years was actually the election of President Rouhani.

Anything that in the future that might be done on Cuba would be done in full consultation, with the real meaning of the word `consultation` that I just alluded to, with this committee.

Congress has played a critical role throughout this negotiation and in the years leading up to these talks, and there is no doubt that Congress will continue to play a role.

I think the sanctions that have been imposed to date are what brought Iran to the table.

I think you ask the $64,000 question. The short answer is we do not know.

We believe that the best way to proceed is based, not only the commitments they make, but also the steps they take to implement those commitments.

We seek to achieve a long-term comprehensive solution to the Iranian nuclear issue.

Thanks to the interim agreement we have reached, the so-called Joint Plan of Action, or JPOA, Iran's program was fundamentally frozen in many key respects.

If our international partners believe that the United States has acted prematurely by adding new sanctions now in the absence of a provocation or a violation by Iran, their willingness to enforce the existing sanctions regime or to add to…

Should Iran refuse a reasonable deal or cheat on its current commitments under the JPOA, the Senate and House could impose additional measures in a matter of hours.

Thank you very much, Mr. Chairman.
