They have already had hearings on Benghazi. There is nothing more to discover.
Actually, that is wrong.....no surprise there.....unless you you can answer these questions still yet to be discovered:
WHO refused the added security that was being begged for by Stevens, of all people?
WHO authorized the stand down order for no attempt to rescue/defend Stevens and the other Americans?
WHO authorized the changing of the talking points in removing all form of "terrorists" & Ansar al-Sharia, which WAS DETERMINED WITHIN HOURS, by the CIA, as the source of the attack, but even weeks later, making it about some obscure video that no one saw??
While Kerry may not be in a position to answer those, and other pressing questions, the notion that there's nothing left to be discovered is pure blinded partisanship
