The Trump family guaranteed the medical expenses, Donald Trump revoked that and has admitted to doing so.
The "guaranteed" it? How did they do that? Did they sign a contract? Obviously not. Otherwise the guy could sue. It sounds to me like it was purely a verbal promise to pay those expenses out of their own pockets. So then when he sued on the will, they would have been paying money to a guy who was suing them. I doubt many paople would sign up for that.
The question you gotta ask is "why didn't he have health insurance?" He obviously could have afforded it.
The whole story sounds fishy.
