Dear Mr. President:

As you know, Iran continues its pursuit of nuclear weapons in defiance of the international community. A nuclear-armed Iran would destabilize the Middle East, weaken America's national security and pose an existential danger to the State of Israel.

Despite its status as a leading oil-producing nation, the Iranian economy depends heavily on imports of gasoline. On July 1st, you signed the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 into law. This bill gave you the power to impose economic sanctions against entities that provide gasoline to Iran. To date, this new law has not been enforced.

Time is not on our side. We urge you to enforce the new sanctions law and seal off Iran's gasoline before it's too late.

Sincerely,
