"CI" likely means counter intelligence, not confidential informants as it is not plural!
It appears from the outside looking in that the CIA, British intel, and State Dept were just as involved and invested in this thing as the 7th floor of the FBI was. We have heard pretty much nothing about it. Nunes is obviously aware of the State Dept, but the CIA and DNI offices have escaped scrutiny to this point. Why? Even John Solomon and Sara Carter, who have arguably been the two most focused investigative journalists on this have said almost nothing about the CIA.
Another great article by Solomon.
The basis for the special counsel continues to erode.
