Yes he does. His assets are pegged at 9+ Billon. His wealth is pegged at 8+ Billion.
He in fact may recognize that he must use it or lose it.
Sorry Trump is not worth $9 Billion. Where did you get that figure, that is what Trump tells everyone but it’s not true.
All through his career Trump has bragged about his net worth and it always turns out he’s lying. I checked Forbes and they peg him at about $4 Billion.
Most of Trump’s wealth are in real estate and not liquid assets such as Bonds or Treasury Notes, and Cash.
So he either sells assets or he borrows against them.
