of facilities offering low or no cost training certificates for residents. As governor, he signed into law the Oklahoma Income Tax Act, which enacted Oklahoma's income tax code. Hall's administration and policy initiatives were opposed and attacked on a regular basis by the state's largest newspaper, the Daily Oklahoman, and its powerful publisher, billionaire Edward Gaylord. Gaylord had supported Hall's opponent, former Governor Dewey F. Bartlett. Unsuccessful re-election bid Hall was unsuccessful in his quest for re-election in the 1974 election. He obtained only 27 percent of the vote, a third-place finish in the Democratic primary. He trailed U.S. Congressman Clem McSpadden and State Representative and Oklahoma Baptist University professor David Boren, who eventually won the nomination (in a runoff) and the general election over Republican Jim Inhofe. Charges and retirement Three days after leaving office in January 1975, Hall was indicted on federal racketeering and extortion charges, in a conspiracy involving Hall and Oklahoma Secretary of State John Rogers willfully steering State of Oklahoma employee retiree funds to investment funds controlled by Dallas, Texas, businessman W. W. "Doc" Taylor. At Hall's trial, Rogers testified that he became an informant after Hall offered him a bribe. Hall was convicted of bribery and extortion, and became the first Oklahoma Governor to be convicted of criminal acts committed during his tenure. After exhausting all appeals, he served 19 months of a three-year sentence at the federal prison in Safford, Arizona. (John Ehrlichman, of Watergate fame, was also housed at the same time at Safford.) Upon his release from prison in 1978, he was disbarred by the Oklahoma Bar Association, which effectively prevented him from practicing law in Oklahoma. Leaving the public spotlight, he moved to La Jolla, California, where he worked in real estate and other ventures. Return to Oklahoma On February 13, 2007, Hall made his first appearance in the state of Oklahoma since he left office over thirty years before. He appeared at the Oklahoma History Center to help launch a new exhibit that features all of the Governors of the State of Oklahoma. Hall remarked that it was "like coming back to heaven." He authored a memoir, 2012's Twisted Justice: A Memoir of Conspiracies and Personal Politics which features his recollections of his time in office, and his reflections on his prison sentence and subsequent career. Death Hall died at a San Diego, California area hospital on May 6,
