FILE - In this July 15, 2013, file photo Sen. John McCain, R-Ariz., is surrounded by reporters as he heads to the Old Senate Chamber for a closed-door meeting on Capitol Hill in Washington. About two months ago McCain likened fellow Republican Sens. Ted Cruz of Texas and Rand Paul of Kentucky, and others to "wacko birds" for their style of confrontational politics. Paul responded a short while later to McCain, the party’s 2008 presidential candidate and a 5th term senator. "The GOP of old has grown stale and moss-covered. I don't think we need to name any names, do we?" Paul said. (AP Photo/J. Scott Applewhite, File)
