keeping the majority of the black vote. After the election, Willkie promised to keep fighting for civil rights. Willkie warned Republicans that only a full commitment to equal rights for minorities would woo African Americans back to the party, and he criticized Roosevelt for yielding to Southern racists among the Democrats. Willkie addressed a convention of the National Association for the Advancement of Colored People (NAACP) in 1942, one of the most prominent politicians to do so up to that point. He urged integration of the armed forces, and when a violent race riot broke out in Detroit in June 1943, he went on national radio in order to criticize both parties for ignoring racial issues. When the movie hearings of 1941 ended without further action, Willkie had been made chairman of the board of Twentieth-Century Fox. In 1943, he worked with Walter White, executive secretary of the NAACP, to try to convince Hollywood to give blacks better treatment in films. Movie moguls promised changes, and some films featured blacks in major roles, but faced with objections from white Southerners, they reverted to giving blacks stereotyped roles after Willkie's death in 1944, such as servants. After his death, the NAACP named its headquarters the Wendell Willkie Memorial Building. On November 9, 1942, soon after making his reports to Roosevelt and the American people, Willkie argued the case of Schneiderman v. United States before the Supreme Court. William Schneiderman, secretary of the California Communist Party, was a naturalized American until the government revoked his citizenship, stating that he had concealed his membership on his application for naturalization in 1927. Two lower federal courts upheld the denaturalization. Representing a communist, even in wartime, did nothing to shore up Willkie's diminishing support in the Republican Party, but he wrote to a friend saying, "I am sure I am right in representing Schneiderman. Of all the times when civil liberties should be defended, it is now." In his argument Willkie quoted Abraham Lincoln and Thomas Jefferson by saying that the people could, if they deemed it necessary, remake the government, and he stated that Marx's view of revolution was mild by comparison. In 1943, the Supreme Court ruled for Schneiderman, 5–3, restoring his citizenship. Although Willkie refrained from criticizing Roosevelt's internment of Japanese Americans, he stated in a speech that war was no excuse for depriving groups of people of their rights. He spoke
