Why would Trump pay for an NDA to keep an affair between Cohen and Daniels quiet?
Because Trump didn't?
Maybe Cohen paid it illegally out of retainer money that Trump gave him for legitimate legal services and Cohen embezzled that money to pay Stephanie Clifford without Trump knowing?
The only evidence that you showed me previously was a CBS News clip discussing a CNN story about a leaked audio by Michael Cohen discussing a payment to Playboy model Karen McDougal that took place several months before the Stephanie Clifford story broke.
I haven't seen any evidence that Trump was aware of payments to Clifford. Maybe Cohen thought he could sneak in a second payment after the McDougal leaked audio came out and then lump it into the growing story about McDougal?
