To fill in the knowledge gaps, this Article proceeds largely in reverse chronological order. First, it reviews Order No. 2507 and related circumstances, finding clear and convincing evidence that the Order did not create the Antitrust Division. Next, the Article examines the prior tenure of AG Cummings, finding clear and convincing evidence that the Antitrust Division existed before Roosevelt became President and Cummings became AG, and that Cummings lowered the standing of the Antitrust Division within the DOJ prior to issuing Order No. 2507. Finally, the Article scours the prior history of the DOJ and determines that the Antitrust Division actually was established in 1919 by Republican AG A. Mitchell Palmer.
