I think this is one of the reasons the GOPe does not want the likes of Trump and/or Cruz to be President. I believe some of the them such as McCain are deeply involved and want to keep their involvement a secret. They don’t want the exposure.

There are several powerful Senators and Congressmen praying to keep this covered up as they were aware of the arms deals. The arms being used by ISIS now came from deals cut by Obama/Hillary in Benghazi. The CIA was involved.
