When Duke's endorsement first aired in Ft. Worth last Friday at the rally where Christie endorsed Trump, Trump disavowed Duke and his endorsement. Typical of the media, once they get something juicy, they repeatedly ask the same or slightly different version of the question. Once they get some wavering of the answer they pounce. Of course, this is only true of their interaction with GOP candidates. Dems, if they ever get asked about something controversial, rarely, if ever, get asked again assuming the Dem candidate even answers the first question.
