In February, 1955, a depressed Cvetic was admitted to St. Francis Hospital in Pittsburgh by his son for a psychiatric evaluation following several days of heavy drinking. Cvetic was readmitted a short time later and received electroconvulsive therapy in March 1955, after which he was released. 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.
