This should not be subject to partisan attacks and political ad wars, even though it has been.

The United States should also press Iran to meet the grievances of American families who lost their loved ones in Iranian-inspired attacks.

I believe, however, that if it is implemented effectively, the agreement will restrict and weaken Iran's nuclear program for more than a decade.

I support this agreement. I would hope that Congress would approve this agreement and strengthen the ability of our country to move ahead.

We have an unusually grave and historic responsibility to assess the consequences, without partisan rancor, without any partisan attacks, to assess the consequences of this agreement.

What happens if Congress rejects the deal? How would we maintain effective enforcement of our sanctions?

I support the Iran nuclear agreement and urge the Congress to vote in favor of it in September.

President Obama should reaffirm publicly and in the most unmistakable terms, his readiness to deploy military force to strike Iran should it violate the agreement.

This is one of the most significant national security issues Congress will face in a generation.

On balance, this alternative is not preferable to the concrete restrictions on Iran's program ensured by the nuclear deal.

We know Iran is a sponsor of terrorism. We know it destabilizes the region.

I think ultimately two things would happen: the Iranians would be strengthened and we would be weakened in the long-range struggle that we are in with them.
