According to THIS, Donald Nixon has been dead for more than 20 years.
When he was alive, the Donald Nixon I remember was always on the fringe of corruption, from bribes and kickbacks (e.g. Hughes Aircraft, Robert Vesco and Bebe Rebozo) to Watergate ... not unlike Hillary's siblings, Hugh and Tony Rodham. He certainly did nothing to honor his famous older brother.
I stand corrected. I was thinking of Richard Nixon’s other brother, Ed.
