They might have his tax forms showing he is a thousandaire.
My personal surmise, based on no evidence whatsoever, is that Trump is real estate rich and cash poor. He lives off proceeds from loans and credit cards, and has precious little liquidity. If for some reason Mar-a-Lago were swamped in a hurricane, or Trump Tower seized by NYC under eminent domain, his wealth would take a possibly fatal hit. He may be in a similar position as the one he was in three decades ago, when he famously had to declare bankruptcy.
The Russian could be holding the threat of demanding immediate payment of the loans they gave him over his head.
