This prosecutor says Mueller may have already subpoenaed Trump

President Trump is reportedly blaming one of his top lawyers in his first years in office – Don McGahn – for Mueller’s progress in the Russia probe. Another Trump lawyer – Jay Sekulow – went on the record to reiterate that Mueller has not issued a subpoena for Trump and that there is no litigation, but former Federal Prosecutor Nelson Cunningham argues that a mystery grand jury witness could be the President himself, or someone close to him.
