The diagram below shows some activities associated with the Cold War mentality as they affected domestic politics: A five oval diagram has the text The Cold War at Home in the center oval. The other ovals have the text: Alger Hiss Case, McCarthy Hearings, and HUAC Investigations. The remaining oval has a question mark in the center. Why would "loyalty oaths" correctly complete the diagram? Truman implemented loyalty oaths for all federal employees. Congress passed legislation requiring all citizens to take loyalty oaths. Hearings were held to investigate people who objected to taking loyalty oaths at work. Congress overrode Truman's veto of loyalty oaths for the military.
