Tennessee Republican Sen. Bob Corker said Sunday that he’s moving ahead with his bill to give Congress a mandatory review of the recent Iran nuclear agreement but that the legislation is still several votes short of veto-proof passage.
Corker, chairman of the Senate Foreign Relations Committee, told “Fox News Sunday” that the GOP-controlled chamber is two or three votes shy of the 67 needed to override a vowed White House veto. Corker said he talked over the weekend to Democratic holdouts to get their votes to reach the veto-proof majority.
