The whole JP Morgan thing happened before all this, they dumped him back in September. A week or so before even that he was talking about dropping Chase on TV, he was upset at not getting face time with Jamie Dimon, and he'd been mad at them on social media before that.

The recent statements about Jews and the "white lives matter" thing are both after that letter. That it was instead retaliation for "his beliefs" is a convenient inference his camp is happy for people to draw though.
