Millions of transactions with vendors over 40 years and they found a handful of cases where he refused to pay, probably because the vendor was at fault somehow. Sigh. I don’t think he has creditors hounding him.
These firms delivered substandard work. The proof is that law firm in the USA story that did not get paid for representing Trump in some of the no-pay nuisance suits. They did substandard work by failing to get favorable settlements for Trump. Ergo, he didn’t pay. I probably wouldn’t either.
