Anyone at Benghazi was likely on covert mission and sworn to secrecy. That’s a problem and would only be divulged in closed hearings. It’s conceivable (BUT HIGHLY UNLIKELY DUE TO HIS BLACK TEFLON COATING) That 0bama could get impeached for reasons we’re not even allowed to know. I suppose it would come out anyway, but a closed hearing could do more damage to him than an open one.
I still can’r figure out why the “Consulate” was so big and then there was even an “Annex” a mile away with several large buildings. That seems like a lot of real estate for the US to have in Benghazi of all places. I wonder why they needed all that space?
