He’s letting them say their piece. U.S. lawmakers will now get a voice on any Iranian nuclear deal, should one be reached by June 30. Obama has agreed to compromise and sign a bipartisan bill that passed — with unanimous support — through the Senate Foreign Relations Committee. It would give Congress a limited time to review any proposal without Obama waiving sanctions. The catch? If lawmakers reject a deal, the president can veto with just 34 senators’ support, which should help the U.S. save face in negotiations with Iran.
