Question: The United States presidential election of 1920 included which Republican Senator who was later exposed for scandal under Teapot Dome?

<P0-S0> Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th President of the United States, serving from March 4, 1921, until his death in 1923. <P0-S1>  At the time of his death, he was one of the most popular presidents, but the subsequent exposure of scandals that took place under his administration, such as Teapot Dome, eroded his popular regard, as did revelations of an affair by Nan Britton, one of his mistresses. <P0-S2>  In historical rankings of the U.S. presidents, Harding is often rated among the worst. <SEP> <P1-S0> The Teapot Dome Scandal was a bribery incident that took place in the United States from 1921 to 1922, during the administration of President Warren G. Harding. <P1-S1>  Secretary of the Interior Albert Bacon Fall had leased Navy petroleum reserves at Teapot Dome in Wyoming and two other locations in California to private oil companies at low rates without competitive bidding. <P1-S2>  In 1922 and 1923, the leases became the subject of a sensational investigation by Senator Thomas J. Walsh. <P1-S3>  Fall was later convicted of accepting bribes from the oil companies and became the first Cabinet member to go to prison. <P1-S4>  No person was ever convicted of paying the bribes, however. <SEP> <P2-S0> The United States presidential election of 1920 was the 34th quadrennial presidential election, held on Tuesday, November 2, 1920. <P2-S1>  The Republicans nominated newspaper publisher and Senator Warren G. Harding from Ohio, while the Democrats chose newspaper publisher and Ohio Governor James M. Cox. <P2-S2>  Incumbent President Woodrow Wilson, a Democrat, in poor health, chose not to run for a third term. <P2-S3>  Former President Theodore Roosevelt had been the front-runner for the Republican nomination, but his health collapsed in 1918. <P2-S4>  He died in January 1919 without leaving an obvious heir to his progressive legacy. <P2-S5>  With both Wilson and Roosevelt out of the running, the major parties turned to little-known dark horse candidates from the state of Ohio, one of the states with the largest number of electoral votes. <P2-S6>  As his running mate, Cox chose Franklin D. Roosevelt, a fifth cousin of Theodore Roosevelt who would be elected president himself in 1932. <SEP> <P3-S0> The United States presidential election of 1996 was the 53rd quadrennial presidential election. <P3-S1>  It was held on Tuesday, November 5, 1996. <P3-S2>  The Democratic national ticket was led by incumbent President Bill Clinton, and his running mate, incumbent Vice President Al Gore. <P3-S3>  The Republican nominee for President was Bob Dole, the former Republican Leader of the United States Senate and long-time Senator from Kansas who was previously the vice-presidential running mate of President Gerald Ford in 1976, following Vice President Nelson Rockefeller's retirement from politics that year. <P3-S4>  Dole's running mate for Vice President was Jack Kemp, a former NFL football player and the Housing Secretary under George H. W. Bush. <P3-S5>  Businessman Ross Perot ran as candidate for the Reform Party with economist Pat Choate as his running mate; he received less media attention and was excluded from the presidential debates and, while still obtaining substantial results for a third-party candidate, by U.S. standards, did not renew his success of the 1992 election. <P3-S6>  Turnout was registered at 49.0%, the lowest for a presidential election since 1924.
