Eric Rauchway talked about his book, Murdering McKinley: The Making of Theodore Roosevelt's America published by Hill and Wang, which recounts how assassin Leon Czolgosz, the late President McKinley, and President Theodore Roosevelt defined the Progressive Era. Mr. Rauchway argued that the progressive leadership of Theodore Roosevelt made Americans and historians alike forget about President William McKinley after his murder. In his research Mr. Rauchway discovered why Czolgosz decided to murder the president. He also describes Theodore Roosevelt at the moment of his ascension to the White House.
