The HUAC was created in 1938 to investigate alleged disloyalty and subversive activities on the part of private citizens, public employees, and those organizations suspected of having communist ties . In 1969, the House changed the committee's name to "House Committee on Internal Security". When the House abolished the committee in 1975, its functions were transferred to the House Judiciary Committee . </P> <P> The committee's anti-communist investigations are often associated with those of Joseph McCarthy who, as a U.S. Senator, had no direct involvement with this House committee . McCarthy was the chairman of the Government Operations Committee and its Permanent Subcommittee on Investigations of the U.S. Senate, not the House . </P>
