We have a congressional source who has knowledge of the Benghazi investigation. Our source wrote to say that these reports of a CIA scandal are bogus:

The bottom line is that the CIA has been exceedingly responsive to us, we have no evidence to substantiate the claims of intimidation, and we interact with CIA personnel of all levels all the time both at official functions and informally. And we have not heard anything that would make me think any of the conspiracy rumors or intimidation rumors are true.

We know what they were doing there (yes, there were such folks on the ground). We knew before the attack. And we have seen nothing to suggest that they were shipping arms to Syria or holding detainees at the annex, both of which would have been outside their authorization. We have been given a very large volume of reports, emails, and intelligence — thousands of pages — and we have met with folks who were on the ground. I see no evidence suggesting the attack was at all related to their specific activities. It was apparently a target of opportunity, and a relatively insecure one at that. We are pretty confident we know the whole story, and I constantly ask reporters to share their unnamed sources with a promise to keep it anonymous and confidential, and they never follow through.
