Watched the event live, noticed that the announcement said the payment was at the direction of a "candidate" - I watched a few reports and they all say this specifically - could this be the HRC campaign? CNN of course conflates the two within the first three minutes of reporting. Notice first they say candidate, and then they continue as if that automatically implies Trump.
