In 1939, Chapman was an early victim of the House Committee on Un-American Activities, as then-chairman Martin Dies, Jr. published a list of the government employees who were members of a Communist-controlled organization (Chapman was considered a member because there was a record that he had contributed two dollars to the American League for Peace and Democracy, which was raising money for the loyalists during the Spanish Civil War).
