House Republicans on Wednesday sharply repudiated Rep. Kevin McCarthy's comments that suggested the Benghazi oversight committee had succeeded by tarnishing Hillary Clinton, saying it undermined their party's messaging on a key issue and raised questions about his ability to be the GOP's top communicator.<br /><br />The California Republican, who is the leading contender to become the next speaker of the House, said Tuesday night that the GOP-led Congress had succeeded by bringing down Clinton's poll numbers because of the long-running investigation into the 2012 terror attack that killed four Americans.<br /><br />"Everybody thought Hillary Clinton was unbeatable, right?" McCarthy said on Fox News. "But we put together a Benghazi special committee, a select committee. What are her numbers today? Her numbers are dropping. Why? Because she's untrustable. But no one would have known any of that had happened had we not fought."<br /><br />Full story: http://edition.cnn.com/2015/09/30/politics/kevin-mccarthy-benghazi-committee-speaker/
