The Reed Smoot hearings (Smoot hearings or Smoot Case) were a series of Congressional hearings on whether the United States Senate should seat U.S. Senator Reed Smoot, who was elected by the Utah legislature in 1903. Smoot was an apostle in The Church of Jesus Christ of Latter-day Saints (LDS Church), one of the top 15 leaders of the church. The hearings began in 1904 and continued until 1907, when the Senate voted. The vote fell short of a two-thirds majority needed to expel a member so he retained his seat.
The premise of the controversy surrounding Smoot's seating in the Senate was claimed to be about the church's practice of polygamy, which the church claimed to have officially abandoned in 1890; as the hearings revealed, however, the practice continued unofficially well into the 20th century. For example, the President of the LDS Church Joseph F. Smith cohabited with his many wives (all of whom he married before 1890) and fathered eleven children after 1890. New plural marriages did end by 1909, but the practice continued until the polygamists died off. Smoot himself only had one wife.
The attorney who represented those protesting Smoot's admittance to the Senate, Robert W. Tayler, explained in his summation that polygamy was irrelevant and the real danger was Mormon belief in revelation. Although it has been claimed that polygamy was largely responsible for deep animosity between the LDS Church and the United States, in reality, it became a cause celebre to help unite Republicans against Democrats. Earlier, when it was well known that Brigham Young was a polygamist, the U.S. President appointed him twice as territorial governor and the Senate ratified the appointment. Much of the American Protestant establishment viewed the LDS Church with distrust. The establishment was also skeptical of Utah politics, which before gaining statehood in 1896 had at times been a theocracy (theodemocracy) and in the early 20th century was still heavily dominated and influenced by the LDS Church.
