Couldn’t he simply forge some documents? He controls the FBI and the DOJ. If they did anything at all - all they’d prop up his lies. Also - he controls the IRA IRS among other things. Trump could have every high-level JPMorgan exec audited for the last 10 years. And since Trump controls every other federal government thing - that could be only the beginning of their pain.

It’s easier and far simpler to give Trump a number and make him stop. Bezos spent $40 million to make Melania’s documentary. It was essentially a fee to please Trump. And he’ll probably only recoup a very tiny amount of that. JPMorgan could offer Trump - I dunno - $100M and keep the deal secret with a mass of NDAs so then Trump could go brag about his big, big win to the media.
