Winners and Losers in the Senate Iran Fight

The weeks-long battle ended with a bipartisan vote, but things got ugly along the way.

WASHINGTON, DC - APRIL 14: Sen. Marco Rubio (R-FL)(Rear), a Republican presidential candidate, passes Sen. Bob Corker (R-TN) 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 and Sen. Ben Cardin 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.
