The chief figures in the network are Charles and David Koch, whose father made his fortune in part by building oil refineries in Stalin's Russia and Hitler's Germany. But these beliefs also advance their personal and corporate interests: many of their companies have run afoul of federal pollution, worker safety, securities, and tax laws.
