FILE - In this 1936 file photo, Jesse Owens of the United States runs in a 200-meter preliminary heat at the 1936 Summer Olympics in Berlin. Owens won four gold medals at the 1936 Berlin Olympics and showed up Adolph Hitler's idea of Aryan supremacy. The Olympic games are supposed to rise above political interests, but an undertone of politics has been present at every Olympics going back at least to the 1936 games. (AP Photo/File)
