U.S. Senators Johnny Isakson, R-Ga., and Bob Corker, R-Tenn., both members of the Senate Foreign Relations Committee, have sent a letter to Secretary of State Hillary Clinton demanding more details regarding the increasing threats and security concerns that preceded the Sept. 11, 2012, attacks on the U.S. Consulate in Benghazi, Libya, that resulted in the death of four Americans, including U.S. Ambassador to Libya, Christopher Stevens.
