Not only that, but he can't use money from his political campaign for his legal battles. I think the latest figure from the court monitor put him at having $400mil on hand (with no Trump Org business transactions in 14 months), so with all the potential fines coming, plus anyone he owes money to, he's very likely insolvent and will have to sell off assets in a hurry or file for bankruptcy.
...or chance it and dip into his political funds, which surely are not being watched by multiple watchdog groups. /s
