With the waning of anti-communism in the 1950s, Cvetic struggled to find buyers who were interested in his story as well as his testimony. As early as 1953, attorneys had declined to utilize him as a witness due to recurring concerns regarding the quality of his testimony. By 1955, Cvetic had been largely discredited as a witness. On April 21, 1955, the Justice Department's Committee on Security Witnesses unanimously recommended that Cvetic not be used as a witness unless his testimony could be corroborated by external sources. This coincided with continued FBI concerns regarding Cvetic's embellishment of the facts, including one instance in which he claimed to have defused a Nazi spy plot single-handedly.
