Trump's verbal accusation today of Bannon having been a White House leaker is the first time this has been explicitly stated, as far as I know.
From POTUS' statement:
>Steve pretends to be at war with the media, which he calls the opposition party, yet he spent his time at the White House leaking false information to the media to make himself seem far more important than he was. It is the only thing he does well. Steve was rarely in a one-on-one meeting with me and only pretends to have had influence to fool a few people with no access and no clue, whom he helped write phony books.
That is an accusation of criminal activity, is it not? Before, it was possible to infer that Bannon was a leaker or that he did not get along with others or was not a team player or left "voluntarily". An inference has changed status to a direct accusation. If it were not provably true, POTUS would not say it.
I am examining the situation for actors playing roles here, but not seeing a scripted drama; rather, serious accusations and genuine anger coming from POTUS.
I believe everything POTUS does is carefully considered and deliberate, down to the timing and often multiple meanings.
Time will tell if this is a script playing out or an actual dispute potentially including criminal conduct by B.
