In 1874 Burton began to read law in the office of Gordon, Brown & Lamb, at Indianapolis, and in 1875 was admitted to the bar. In the spring of that year, he married Mrs. Carrie Webster of Princeton. In 1876 Mr. Burton was nominated by the Republicans for presidential elector and made many speeches during the campaign. In 1878 he moved to Abilene, Kansas, where he formed a partnership with Judge John H. Mahan for the practice of law.
Politician
He was elected to the Kansas House of Representatives in 1882; was re-elected in 1884 and again in 1888; and was appointed a member of the World's Fair Columbian Commission at Chicago in 1893, representing Kansas. In 1895 Burton lacked but one vote of being the Republican Party nominee for United States Senator. But in January 1901, he was elected Senator and began service on March 4, 1901. While in the Senate, he was chairman of the Committee on Forest Reservations and Game Protection. He served until June 4, 1906, when he resigned.
Corruption conviction
On January 23, 1904, Burton was indicted by a Federal grand jury at St. Louis, Missouri, on the charge of having accepted $2,500 from the Rialto Grain and Securities company, to represent Rialto before the Post Office. He was to have prevented the issuance of a fraud order against the company, thus denying it the use of the US mails. Burton was tried before Judge Adams of the U.S. District Court for the Eastern District of Missouri, in St. Louis, found guilty in March and sentenced to pay a fine of $2,500 and serve six months in the jail at Ironton, Missouri. He appealed the case to the United States Supreme Court, which in January 1905, reversed the decision of the district court, on the grounds that the venue was improper since the money was paid to Burton in Washington, D.C, and remanded the case for a new trial there. The second trial was before Judge Van Devanter of the United States circuit court. In November 1905 he was given the same sentence. A second appeal to the Supreme Court followed, and this time the decision of the lower court was sustained. On June 4, 1906, Burton resigned from the Senate.
Later life
After his resignation, he returned to his law practice in Abilene and engaged in the newspaper business. Joseph Burton died in Los Angeles, California in 1923; the body was cremated and the ashes deposited in the columbarium of the Los Angeles Crematory Association. The ashes were removed in 1928 for burial in the Burton family plot in Abilene Cemetery.
