This story from 9/12 said troops were sent from Tripoli. Marines.
Big Gov layer reported no Marines were in Libya at the time.
Any of this cleared up later?
What I read a few days back was that an 8-member team was sent from Tripoli. One of the former Navy Seals who was killed, was a member of that team.
It did not detail the makeup of the rest of that team. I got the Idea that it was a CIA security group, but that was not explicitly stated.
