As Director of the Office of War Information, Davis recommended to President Roosevelt that Japanese-Americans be permitted to enlist for service in the Army and Navy and urged him to oppose bills in Congress that would deprive Nisei of citizenship and intern them during the war. He argued that Japanese propaganda proclaiming it a racial war could be combated by deeds that counteracted this. Davis has been termed one of the "unsung forefathers" of the 442nd Regimental Combat Team, an all-Nisei combat unit in the war.
