The answer is simple: Obama's Muslim, terrorist, murdering buddies who he helped put into power with his "Arab Spring" initiative attacked the US ambassador in Benghazi, captured him alive, SODOMIZED him and then brutally KILLED him in the name of "allah" their bloody moon god who is none other than Satan himself. All the while OBAMA denied the numerous, urgent request from the people on the ground asking Obama and his minions for HELP.
OBAMA LET THEM DIE! This whole bloody mess is on his (and Hillary Clinton's hands. That is the simple truth and people can cry and beg this godless administration to tell the truth, they can call congress until Hell freezes over but NOTHING will EVER come of it and the truth will never come out because if it did, Obamessiah would be impeached and both he and Hildabeast would be in prison and that my friends is never going to happen because those in power are evil. They know this is the truth but they do nothing because they are either mindless worshipers of Obamessiah or they are AFRAID of what Obamessiah and the head of the INJUSTICE Department Holder will do to them.
