Rubio pans Dems for 'walking the plank' on Iran deal Sen. Marco Rubio lit into Democrats supporting the Iran nuclear deal Friday after 42 of them blocked a resolution that rejected the deal on Thursday. During an interview with Fox News' Martha MacCallum, the 2016 hopeful called out Democrats for "walking the plank" by supporting the deal after seeing how Sen. Charles Schumer was treated by the administration after he came out against the agreement in August. Rubio also argued that Democrats who backed the agreement have "become captive to a radical element in their party." "They know it's a bad deal. The Democrats know it's a bad deal," Rubio said. "That's why they all couched their terms in the sense of 'I don't think it's perfect, I don't think it's ideal.'"
