“During a speech in Wheeling, West Virginia, Senator Joseph McCarthy (Republican-Wisconsin) claims that he has a list with the names of over 200 members of the Department of State that are “known communists.” The speech vaulted McCarthy to national prominence and sparked a nationwide hysteria about subversives in the American government.”
“To be sure, McCarthy was not the first to incite anxiety about subversive communists. Congress had already investigated Hollywood for its supposed communist influences, and former State Department employee Alger Hiss was convicted of perjury in January 1950 for testimony dealing with accusations that he spied for the Soviet Union during the 1930s. But McCarthy went a step further, claiming that the U.S. government, and the Department of State in particular, knew that communists were working in their midst.”
