Despite the valuable information provided to the FBI by Cvetic, his increasingly erratic behavior began to undermine his credibility with both the Bureau as well as the CPUSA. As early as 1946, Cvetic had been identified as a potential FBI mole by Hearst reporter James Moore. In 1947, Cvetic was arrested for drunk and disorderly conduct and while in the Pittsburgh city jail allegedly shouted "you can't do this to me, I work for the FBI!" In addition, Cvetic had difficulty maintaining his cover and, by his own admission, had admitted to several people that he worked for the FBI, including his brother, his psychiatrist, and "more than one girl." By 1947, the FBI was considering discontinuing the use of Cvetic as an informant due to his security breaches, but ultimately decided to continue employing him.
