problem. We have an independent FEC in this country whose job is enforcing campaign finance law and FEC didn't say Trump's payment is an violation of campaign finance law. We also have a bunch of politically motivated prosecutors who want to charge president on the ground of violation of campaign finance law. The question is whether Trump would have made this payment even if he had not been a presidential candidate. The answer is an easy Yes. Just like many celebrities (e.g. Christian Coronado...) do same thing. Cohen was hired years before Trump started his presidential campaign to handle this kind of thing. So, the payments to porn stars clearly has personal purpose. If it's for personal reason, it's not an violation of campaign finance law. That's perhaps the reason why FEC doesn't think it's an violation of law.
