 After the attack on Pearl Harbor and the declaration of war in December 1941, the anti-interventionist movement (such as the America First Committee) sputtered out, and isolationists like Coughlin were seen as being sympathetic to the enemy.In 1942, the new bishop of Detroit ordered Coughlin to stop his controversial political activities and confine himself to his duties as a parish priest.William Dudley Pelley founded (1933) the antisemitic Silvershirt Legion of America; nine years later he was convicted of sedition.
