He was admitted to the bar in 1901 and commenced practice in Paducah, McCracken County, Kentucky. He was prosecuting attorney for McCracken County from 1905 to 1909 and judge of McCracken County Court from 1909 to 1913. He was elected as a Democrat to the Sixty-third and to the six succeeding Congresses (March 4, 1913 - March 4, 1927) He did not seek renomination in 1926, having become a candidate for United States Senator.
