 In 1942, Iowa Congressman Vincent Harrington enlisted in the United States Army Air Corps, and initially took a leave of absence from his seat in Congress.However, President Roosevelt ordered all military officers holding dual positions in Congress to resign from one position or the other, which prompted Harrington to remain in the Air Corps and therefore resign from Congress, in September 1942.His resignation prompted Governor George A. Wilson to add a ballot item to the November 1942 to elect a successor to fill Harrington's seat from the last few months of the Seventy-seventh Congress.
