or communists, Congress passed the Per Centum Act of 1921, signed by Harding on May 19, 1921, as a quick means of restricting immigration. The act reduced the numbers of immigrants to 3% of those from a given country living in the U.S., based on the 1910 census. This would, in practice, not restrict immigration from Ireland and Germany, but would bar many Italians and eastern European Jews. Harding and Secretary of Labor James Davis believed that enforcement had to be humane, and at the Secretary's recommendation, Harding allowed almost 1,000 deportable immigrants to remain. Coolidge later signed the Immigration Act of 1924, permanently restricting immigration to the U.S. Eugene Debs and political prisoners Harding's Socialist opponent in the 1920 election, Eugene Debs, was serving a ten-year sentence in the Atlanta Penitentiary for speaking against the war. Wilson had refused to pardon him before leaving office. Daugherty met with Debs, and was deeply impressed. There was opposition from veterans, including the American Legion, and also from Florence Harding. The president did not feel he could release Debs until the war was officially over, but once the peace treaties were signed, commuted Debs' sentence on December 23, 1921. At Harding's request, Debs visited the president at the White House before going home to Indiana. Harding released 23 other war opponents at the same time as Debs, and continued to review cases and release political prisoners throughout his presidency. Harding defended his prisoner releases as necessary to return the nation to normalcy. Judicial appointments Harding appointed four justices to the Supreme Court of the United States. When Chief Justice Edward Douglass White died in May 1921, Harding was unsure whether to appoint former president Taft or former Utah senator George Sutherland—he had promised seats on the court to both men. After briefly considering awaiting another vacancy and appointing them both, he chose Taft as Chief Justice. Sutherland was appointed to the court in 1922, to be followed by two other economic conservatives, Pierce Butler and Edward Terry Sanford, in 1923. Harding also appointed six judges to the United States Courts of Appeals, 42 judges to the United States district courts, and two judges to the United States Court of Customs Appeals. Political setbacks and western tour Entering the 1922 midterm congressional election campaign, Harding and the Republicans had followed through on many of their campaign promises. But some of the fulfilled pledges,
