we have to pass it to not know what's in it

According to the IAEA, the Iran agreement negotiators, including the Obama administration, agreed that the IAEA and Iran would forge separate arrangements to govern the inspection of the Parchin military complex – one of the most secretive military facilities in Iran – and how Iran would satisfy the IAEA’s outstanding questions regarding past weaponization work. Both arrangements will not be vetted by any organization other than Iran and the IAEA, and will not be released even to the nations that negotiated the JCPOA. This means that the secret arrangements have not been released for public scrutiny and have not been submitted to Congress as part of its legislatively mandated review of the Iran deal.

Ну правильно, как же без секретных протоколов-то.
