The House Un-American Activities Committee holds first-ever televised congressional hearing: "Confrontation Day" between Whittaker Chambers and Alger Hiss.

The House Committee on Un-American Activities (HCUA), popularly the House Un-American Activities Committee (HUAC), was an investigative committee of the United States House of Representatives created in 1938. Their goal was to investigate alleged disloyalty and subversive activities on the part of private citizens, public employees, and those organizations suspected of having communist ties. It became a standing (permanent) committee in 1946. Then, from 1969 and onward, it was known as the House Committee on Internal Security. When the House abolished the committee in 1975, its functions were transferred to the House Judiciary Committee.
