In the session where Trump asked several contestants in his "what was my demeanor"? quiz, twice, including immediately before asking the first person, he predicated what he was asking by saying the Democrats "always" create the narrative that he leaves meetings "yelling and screaming".
Yet, in the Pelosi/Schumer presser after the broken meeting, all Pelosi would say about his appearance was "well, I won't even characterize it." Schumer said what he saw "would make your jaw drop". In her solo presser the next day, Pelosi said he "stormed" out of the room, and she pounded her fists twice on her lecturn, to imitate Trump's display before he left. I suspect, just a guess, that that might be what Schumer was referring to. And that's pretty believable to me. Nobody said he left the meeting "yelling and screaming".
But this is what Trump does. Makes up "yelling and screaming" before listening to his attendees echo his claim of calmness. He overstates what Pelosi and Schumer said, in order to enhance his victim card.
And in that same session, he brings up the central motif of his victim card. He was the victim of an attempted ”coup", a "takedown of the president". This is the theme he is selling his ardent followers, his base. It lends itself naturally to that base's belief that it has always been exactly as he himself said: they've been trying to take him down since he descended the escalator.
We should expect AG Barr to develop information from declassified documents to support this victim narrative. He will find something(s) that can be interpreted as helping Trump, and he will say not one word on anything that would reflect poorly on Trump. Which will be used through the election cycle.
This is banana republic stuff.
