a total of 2 years in any national government office. He didn't know that food stamp allocations have been a part of the Farm bill for decades when he 'served' in the House for a single term.

Someone encouraged this freshman senator. Who wrote the Farsi translation that accompanied his letter? Its someone who has confused the international non-binding (non-treaty) agreement that Obama and the other 5 nations are working on, with a treaty.

All the 47 Republicans mistakenly think this is a treaty, a "binding international agreement", and they self righteously warn that "anything not approved by Congress is a mere executive agreement.”

Zarif emphasized that if the current negotiation with P5+1 result in a Joint Comprehensive Plan of Action, it will not be a bilateral agreement between Iran and the US, but rather one that will be concluded with the participation of five other countries, including all permanent members of the Security Council, and will also be endorsed by a Security Council resolution.

Zarif expressed the hope that his comments “may enrich the knowledge of the authors to recognize that according to international law, Congress may not modify the terms of the agreement at any time as they claim, and if Congress adopts any measure to impede its implementation, it will have committed a material breach of US obligations.
