I believe the coverup is to protect the Muslim Americans brought in to the State Dept. and government to counsel the administration on sensitivity towards Muslims in the ME, specicifically the Muslim Brotherhood. I think that is why security was pulled, and help was denied. I think they had a “go to” group of muzzies in the admin they gave deference to regarding these problems and followed their advice. Obama will protect them, names and his turning national security over to them, until his dying day.
