In 1940, Priest was encouraged to run for the United States House of Representatives as an independent in Tennessee's 5th congressional district, which is based in Nashville. He won in an upset, defeating the incumbent, one-term Democratic Congressman Jo Byrns Jr. Upon swearing-in, he immediately joined the Democratic caucus, and was reelected seven times. The district was renumbered the 6th District in 1943 and became the 5th once again in 1953. He served as the House majority whip between 1949 and 1953. Priest was one of three Democrats in the Tennessee House delegation who did not sign the 1956 Southern Manifesto, the others being Joe Evins and Ross Bass.
At the time of his death, Priest was serving as the chairman of the House Commerce Committee and had already secured the Democratic nomination for a ninth term, which had essentially assured him of reelection since no Republican has been elected to the U.S. House of Representatives from Nashville since Reconstruction.[citation needed]
Death and legacy
In early October 1956, Priest entered a Nashville hospital for an operation on an ulcer and was reported in satisfactory condition. However, complications developed and he died in the early morning hours of October 12.[2]
In August 2010, it was announced that Priest's papers, along with the research files of Rebecca Stubbs, author of the biography J. Percy Priest and His Amazing Race, had been donated to the Tennessee State Library and Archives.[4]
