In any event, Congress was not provided with these side deals as required by the Corker bill, so the 60-day review never legally commenced. And since it appears they can never be provided to Congress because they are not available, the period for review may conceivably never commence, ergo the required review, at least as understood by the Corker bill, may never take place.
And this would not be of mere academic interest. “Corker” also provides that until Congress completes its deliberations over the nuclear agreement, the president cannot “waive, suspend, reduce, provide relief from, or otherwise limit the application of statutory sanctions with respect to Iran.” Yet a principal part of the Iran nuclear agreement is that the United States must remove the economic sanctions on Iran that Congress imposed.
If Congress makes a real effort to sort this out, the Iran nuclear deal may not be a slam-dunk after all.
