>No way it was Sessions/Kelly imo.
I don't think so, either, unless they played along.
I can think of Tillerson, Mattis, Sessions being replaced. Any other cabinet members who left?
At this point you you have to figure there was counterintelligence being run by POTUS's guys,so I don't think we can say for sure if those replaced cabinet members were just assets who had to be ex-filtrated or not.
