 The entry of the United States into World War I in April ended Landis's determination to resign; a firm supporter of the war effort, he felt he could best serve the country by remaining on the bench.Despite this decision and his age, fifty, Landis wrote to Secretary of War Newton D. Baker, asking him to take him into the service and send him to France, where the war was raging.Baker urged Landis to make speeches in support of the war instead, which he did.
