He noted that recent Welsh victims of quarry accidents were "a high class of workman –not cheap foreign labor." Late in his congressional career, he sponsored a bill to promote women's suffrage. On behalf of the National Child Labor Committee he offered another to end child labor in most American mines and factories. Wilson found it constitutionally unsound and after the House voted 232 to 44 in favor on February 15, 1915, he allowed it to die in the Senate.
