John McCain's Benghazi Committee Plan Would Give Senator New Relevance 16 Nov 2012 Just four years ago, John McCain was the leader of the GOP. Today, he's the highest-ranking Republican on the Senate Armed Services Committee, a perch from which the former fighter pilot is deeply engaged in the national conversation over war, terrorism and intelligence gathering. But in January, the Arizona senator will lose his top-ranking committee seat due to term limits. The only ranking Republican spot available to him next session will be on the Indian Affairs Committee. Unless, that is, the Senate creates a brand-new select committee. On Wednesday, McCain, flanked by Sens. Lindsey Graham (R-SC) and Kelly Ayotte (R-NH), proposed just that: a select committee with extensive authority to investigate the Benghazi, Libya, attack and the U.S. government's response.
