Rockwell went on to describe him as "one of the most intelligent, cleverest men here..." In the interview Rockwell acknowledged that Jews were a race but not necessarily natural born villains. Rockwell thought Jews because of their arrogance and belief in being a “chosen people” were made and not necessarily born the way they are.
