At the "Tribune", Benchley, along with new editor Ernest Gruening, was in charge of a twelve-page pictorial supplement titled the "Tribune Graphic". The two were given a good deal of freedom, but Benchley's coverage of the war and focus on African-American regiments as well as provocative pictorials about lynching in the southern United States earned him and Gruening scrutiny from management. Amid accusations that both were pro-German (the United States was fighting Germany at the time), Benchley tendered his resignation in a terse letter, citing the lack of "rational proof that Dr. Gruening was guilty of...charges made against him..." and management's attempts to "smirch the character and the newspaper career of the first man in three years who has been able to make the "Tribune" look like a newspaper."
