If this is just an inquiry into the shootout at the embassy, its a joke and theater. What needs to be exposed is the CIA/State dept operation to ship weapons from Benghazi, to Turkey, to be given to Al Qeida/ISIS in Syria.
The rest is window dressing and a distraction.
It is much bigger than that. It involves Morsi, Erdogan, and destruction of nations for the benefit of the Muslim Brotherhood Terrorists.
Yes, Obozo financed election fraud in Egypt with US Gov Dollars and put Morsi in place as President of Egypt. Stole that election. Yes, the Egyptians revolted in mass and el Sisi refused to fire on Egyptian citizens to put it down. He knew/knows the TRUTH. And if pressed by the Egyptian government Morsi will squeal like a dying rabbit.
