In 1947 Joseph McCarthy ordered a background check on all civilians who worked for the government. McCarthy wanted to ensure there were no communist spies working in the government.
On February 20, 1950, McCarthy addressed the Senate and made a list of dubious claims against suspected communists. He cited 81 cases that day. He skipped several numbers, and for some cases repeated the same flimsy information. He proved nothing, but the Senate called for a full investigation. McCarthy was in the national spotlight.

"The teachings of Communism are directed toward one final result—world revolution and the triumph of international Communism. The achievement of this aim would mean the violent and complete destruction of the American Government." -J. Edgar Hoover
Following World War II, Hoover became a zealous and high-profile anti-Communist. He focused on the putative threat of Communist subversion. The FBI played a significant role in the investigation of alleged Communist sympathizers and spies in the federal government. Hoover led the bureau in a thoroughgoing string of investigations intended to snuff out subversive activities not only within the government, but the private sector as well.
The Communist Control Act is a piece of United States federal legislation, signed into law by President Dwight Eisenhower on 24 August 1954, which outlawed the Communist Party of the United States and criminalized membership in, or support for the Party or "Communist-action" organizations and defined evidence to be considered by a jury in determining participation in the activities, planning, actions, objectives, or purposes of such organizations.
