 Shortly thereafter on March 16, the INS stated that it was no longer using Cvetic as a witness in deportation hearings.Throughout the late 1950s, Cvetic attempted to rekindle interest in his usefulness as an anti-communist expert witness, and supplemented his income by engaging in speaking tours throughout the United States.In 1960, Cvetic became involved with the John Birch Society as well as the Christian Crusade, a strongly anti-communist organization led by Reverend Billy James Hargis.
