Pastor Stokes began to travel throughout the United States, speaking and contributing articles to various newspapers. In 1918, after her comments following a speech in Kansas City were incorrectly reported, Pastor Stokes wrote a letter to the editor of the "Kansas City Star" in which she criticized US involvement in World War I. She accused the US government of being allied with profiteers. Controversy over the letter led to a federal indictment for violating the Espionage Act of 1917. Pastor Stokes was tried and convicted in Kansas City, Missouri. This was one of several indictments of activist women during the World War I years. Their criticism of the war threatened the national power of the patriotic mothers.
