Mary Trump is scheduled to be on the Rachel Maddow show tomorrow (Thursday, July 16).

From what M. Trump says, the father, Fred Trump, sr, was a real piece of work. So far I haven't heard any discussion of *his* father; DJT's grandfather emigrated from Germany. The story goes that he immigrated to America to avoid military duty in Germany and that later he petitioned the German government to allow him to return but was denied.
