Huma Abedin’s relatives are Muslim Brotherhood, so there could have been som e back channel communication.
It would explain why they didn’t send anyone to help, AND why they told the CIA post a few kilometers away, to stand down as well.
It would explain why they didn’t secure the site for weeks afterwards, destroying any forensic evidence.
It would explain why they don’t want to catch any of the perpetrators, lest they reveal the true story.

The secret arms deal was extended to so-called moderate forces in Syria through an arms transfer via Turkey. That was why the Turkish Ambassador met with Ambassador Stephens that night before the attack on the consulate.
The large CIA presence was running the arms project out of Benghazi since that was the location of the original rebel command post in Libya. It’s possible that the CIA was trying to get some of the arms back from the Libyan rebels to trans-ship them to Syria via Turkey.
