So here's the REAL story:

Ambassador Stevens was sent to Benghazi to secretly retrieve US made Stinger Missiles that the State Dept had supplied to Ansar al Sharia in Libya WITHOUT Congressional oversight or permission.

Sec State Clinton had brokered the deal through Ambassador Stevens and a Priv Arms Dealer named Marc Turi, but some of the Stinger Missiles ended up in Afghan where they were used against our military. On 07/25/12, a US Chinook helicopter was downed by one of them. Not destroyed only because the idiot Taliban didn't arm the missile. The helicopter didn't explode, but it had to land and an ordnance team recovered the missile’s serial number which led back to a cache of Stinger Missiles kept in Qatar by the CIA.

Obama and Hillary were in full panic mode, so Ambassador Stevens was sent to ghazi to retrieve the rest of the Missiles. This was a "do-or-die" mission, which explains the Stand Down Orders given to multiple rescue teams at the US Embassy.

Part 2 belo

It was the State Dept, NOT the CIA, that supplied the Stinger Missiles to our sworn enemies because Gen. Petraeus at CIA would not approve supplying the deadly missiles due to their potential use against commercial aircraft. So then, Obama threw Gen. Petraeus under the bus when he refused to testify in support of Obama’s phony claim of a “spontaneous uprising caused by a YouTube video that insulted Muslims.”
Obama and Hillary committed TREASON!

THIS is what the investigation is all about, WHY she had a Private Server, (in order to delete the digital evidence), and WHY Obama, two weeks after the attack, told the UN that the attack was the result of the YouTube video, even though everyone KNEW it was not.
