The Truman Federal Employee Loyalty Program was a program that required all federal employees to submit to questioning and to face dismissal if they were believed to be disloyal. This program was in response to the Cold War and the possibility of communistic threats in the federal government.
The Truman Federal Loyalty Program was placed under the Civil Service Commission review board and looked for individuals who were members of various threatening groups such as communist, fascist or totalitarian groups. The program was signed into action as Executive Order 9835 by President Truman. The action was made in part due to the concern by the public rather than by governmental officials that there were impostors working in the government.
