AQIM (AQ in the Islamic Mahgreb), the group that attacked the refinery, has been active throughout that area and was certainly involved in the Benghazi incident. They are multinational and some of their members are Egyptians.
I would not be in the least surprised if Obama releases the blind sheik to them as a “gesture of goodwill.”
If Obama releases the sheik we will absolutely know that someone in the ME has the goods on Obama and Benghazi.
