On Bannon's War Room Pandemic just now: "Our fans love terminology… please explain…"
Guest said Brennan ran coup out of a "Fusion Cell" or "Counter-Intelligence Work Group." Guest went on to say that using the term "Counter-Intelligence" it allowed Brennan and the group to skip a lot of the bureaucracy within the CIA and keep things secret from prying eyes. It allowed people to be given tasks without having to explain why they were doing it.
