“...despite already having signed a detailed letter admitting that there was no affair. Prior to its violation by Ms. Clifford and her attorney, this was a private agreement. Money from the campaign, or campaign contributions, played no roll in this transaction.”
IF Trump paid her off from his own funds that is not illegal. I believe they will claim he used campaign donations for the payoff.

Then he is in the wrong courtroom if there is a violation of federal campaign finance law, which isn’t a felony in this amount in any case.
There were no campaign funds sent to Horseface.
