<P> In just over 26 months, from April 14, 1917, to June 30, 1919, it used every medium available to create enthusiasm for the war effort and to enlist public support against the foreign and perceived domestic attempts to stop America's participation in the war . It used mainly propaganda to accomplish its goals . </P> <P> President Woodrow Wilson established the Committee on Public Information (CPI) through Executive Order 2594 on April 13, 1917 . The committee consisted of George Creel (chairman) and as ex officio members the Secretaries of: State (Robert Lansing), War (Newton D. Baker), and the Navy (Josephus Daniels). The CPI was the first state bureau covering propaganda in the history of the United States . </P> <P> Creel urged Wilson to create a government agency to coordinate "not propaganda as the Germans defined it, but propaganda in the true sense of the word, meaning the' propagation of faith ."' He was a journalist with years of experience on the Denver Post and the Rocky Mountain News before accepting Wilson's appointment to the CPI . He had a contentious relationship with Secretary Lansing . </P> <P> The purpose of the CPI was to influence American public opinion toward supporting U.S. participation in World War I via a prolonged propaganda campaign . The CPI at first used material that was based on fact, but spun it to present an upbeat picture of the American war effort . In his memoirs, Creel claimed that the CPI routinely denied false or undocumented atrocity reports, fighting the crude propaganda efforts of "patriotic organizations" like the National Security League and the American Defense Society that preferred "general thundering" and wanted the CPI to "preach a gospel of hate ." </P>
