The Iran Nuclear Agreement Review Act of 2015 (INARA) (H.R. 1191, Pub.L 114–17) is a bill that was passed by the US Congress in May 2015, giving Congress the right to review any agreement reached in the P5+1 talks with Iran aiming to prevent Iran from obtaining nuclear weapons.
The bill passed in the Senate by a 98–1 vote (only Tom Cotton voted against), and then passed in the House by a vote of 400–25 on May 14.[1] President Barack Obama threatened to veto the bill, but eventually a version arrived that had enough support to override any veto and Obama did not try vetoing it.
A group of Republican Senators said an agreement to return to the [Joint Comprehensive Plan of Action] (JCPOA) required congressional review under INARA, while others said the JCPOA has already been through such a review.[3]
