The Loyalty Review Board and the House Un-American Activities Committee were created for the purpose of seeking out communist supporters and investigating individuals suspected of being disloyal to the US government.
1. **Loyalty Review Board:** This board was established by President Truman in 1947 to screen federal employees for loyalty to the United States government. It aimed to identify and remove any employees deemed disloyal, particularly those with suspected communist ties during the height of the Red Scare.
2. **House Un-American Activities Committee (HUAC):** The HUAC was a congressional committee established in 1938 to investigate alleged disloyalty and subversive activities, with a particular focus on communist infiltration in American society. It conducted high-profile investigations into Hollywood figures, government officials, and others suspected of being un-American.
In summary, both the Loyalty Review Board and the House Un-American Activities Committee were tools used to combat perceived threats of communism and disloyalty in the United States during the Cold War era.
