Sundance was reporting weeks ago that Priestap and Page were cooperating. It became clear from something that was released involving the committee and the IG, but I don’t recall what specifically made clear that such was the case. No MSM outlets picked up on it. As for Strzok, I don’t recall if anyone has said that he is cooperating before, but since he is still employed, it makes sense that it is because he is cooperating.
Good signal to sepculate from!
