Maybe an ongoing situation (hostage or other) where the Libyan terrorists are pulling the strings and ordering the officials to do what they tell them “or else...”.

Otherwise, nothing makes sense. A cover up is not done in such a large way and Hillary has VAST experience at how cover ups are done.
