It looks like it may be more than just the payment to Stormy Daniels. It appears to involve a whole bunch of falsification of business records. Perhaps also those differing valuations of Trump properties and the school fees for directors of Trump inc. that were treated as business expenses and not compensation. But maybe those are in the hands of Letitia James.
I wonder if his imprisoned accountant has finally turned on him. Because if he hasn't, Trump will attempt to make him the fall guy, in the usual way.
