There is confusion about that. I heard it as: THE CIA, meaning headquarters, did not make any requests for military backup for Benghazi. That stops things at the CIA and covers Obama's a** and the Pentagon's.
There have been many stories that there were requests for backup from personnel in Benghazi, maybe too many to deny.
And then there was this statment from the CIA on October 26:
"No one at any level in the CIA told anybody not to help those in need; claims to the contrary are simply inaccurate."
Well, If I understand it correctly, the former seals were working for a private security firm, (Blue Mountain). Therefore, their boss would be their superior in the security firm - not the CIA or Pentagon.
