He served in the 55th United States Congress, March 4, 1897 to March 3, 1899, and was an unsuccessful candidate for reelection in 1898.

Later career

In addition, he started a socialist newspaper, The Lantern, and his editorials and stories on topics including birth control, labor rights, and labor unions angered mine owners and other business leaders, which resulted in scrutiny by law enforcement agencies and other government officials. In 1908 he was charged with sending obscene material through the mails, and sentenced to a year in prison.^[1]
