WASHINGTON, DC - APRIL 14: Sen. Rand Paul (R-KY) (Rear), a Republican presidential candidate, passes Sen. Marco Rubio (bottom), a Republican presidential candidate, as senators make their opening remarks during a markup meeting of the Senate Foreign Relations Committee on the proposed nuclear agreement with Iran April 14, 2015 in Washington, DC. A bipartisan compromise reached by Sen. Bob Corker (R-TN) and Sen. Ben Cardin (D-MD) would create a review period that is shorter than originally proposed for a final nuclear deal with Iran and creates compromise language on the removal of sanctions contingent on Iran ceasing support for terrorism.
