my understanding is that he had "fluctuating debt in the thousands". i got the distinct impression that they were adding up all his credit card charges over the course of over a decade rather than stating the largest amount of debt that he ever carried.
i never did receipts for my games either.
i don't know what to tell you other than if he was lying about this he shouldn't be on the court and if he goes on the court he should be impeached for it. but if what he says is the truth and i see no reason to think otherwise then it's what he says
