Answer:
Charles Schenck's opposed America's involvement in World War I.
Step-by-step explanation:
Charles T. Schenck was an executive secretary in the Socialist Party of the United States. During the time when America decided to participate in World War I, Schenck produced and circulated some 15,000 leaflets, urging people not to participate in the war. The leaflets were drafted to insist men resist military service. Consequently, he was convicted under the Espionage Act of 1917, for using words that might create danger or threat to the nation.
Therefore, Schenck's stance was that he opposed America going into World War I.
