Here's the recap: Former House Speaker Marco Rubio said the charges on his party's credit card were paid "with my money." There is some evidence on both sides. On one hand, Rubio is able to document that he made payments to American Express for items that he declared to be personal. That supports his contention that it was his money. But the fact that there were purchases that appear to be personal, and were paid for by the Republican Party, undercuts his claim. And although the card was under his name, American Express says that in general -- as long as a cardholder isn't violating the rules set out by the company -- it is the company (in this case the party) that is liable for the charges. And the cardholder (in this case Rubio) won't have his credit rating affected if the bill is not paid on time. So there's little evidence that it was "his money," but more that it was really the party's. We rate his claim Barely True.
