Introduction

On January 21, 1950, a federal grand jury indicted Alger Hiss, a former State Department official, on perjury charges related to his spy work for the Soviet Union during the 1930s. Also in 1950, Klaus Fuchs, who had worked on the American atomic bomb, confessed to being a Soviet spy while doing so, and implicated others, revealing a Soviet espionage network that had acquired significant classified information about America’s atomic bomb program. His confession ultimately led to the arrest, trial, and conviction of several other people, including Julius and Ethel Rosenberg, who were executed in 1953.

Senator Joseph McCarthy (R-Wisconsin), a first-term senator, was not a well-known figure when he spoke at an event sponsored by the League of Women Voters in Wheeling, West Virginia, shortly after the Hiss indictment. Taking this news as his theme, he claimed that 205 State Department employees were members of the Communist Party of the United States of America and that Secretary of State Dean Acheson was protecting them. In subsequent speeches, McCarthy cited different numbers – eighty-one, then fifty-seven – without providing much corroboration. (After the Cold War, newly accessible Soviet files revealed that over 500 Americans, including journalists and other ranking government officials besides Hiss, had spied or worked for the Soviet Union in the 1930s and 1940s. See John Earl Haynes, Harvey Klehr, and Alexander Vassiliev, Spies: The Rise and Fall of the KGB in America [New Haven: Yale University Press, 2009]. McCarthy knew nothing of this.)

Problems with McCarthy’s evidence did not diminish the massive attention he and his charges received. (Nor did the existence of a federal employee loyalty program that President Harry Truman had implemented in 1947.) The Hiss case, the communist victory in China (1949), the Soviet development of atomic weapons (1949), and the outbreak and early stages of the Korean War (1950) fed the impression that the United States was losing the Cold War. According to McCarthy, subversives within the U.S. government were responsible.

McCarthy’s charges, the espionage trials, and growing Cold War tension led Congress to pass the Internal Security Act on September 20, 1950. President Truman vetoed the act on September 23. His veto was overridden by both houses of Congress on the same day. Various provisions of the law were subsequently overturned by the Supreme Court or repealed by Act of Congress. As for McCarthy, some Senators opposed him early on (most prominently Margaret Chase Smith, R-Maine), but he continued to command attention for several years, summoning people to Senate hearings and publicly accusing them of disloyalty and treason. He was eventually censured by the Senate for his conduct (December 2, 1954). After that, he ceased to be an influential public figure. He died in 1957.

Discussion Questions

A. The Internal Security Act states that it should not be construed to restrict freedom of speech or press.  Was President Truman right to think it would? Section 4a of the Act prohibits establishing a totalitarian government except by constitutional amendment. If it is wrong to vote or campaign for such a government, w
