FBI True arrived on CBS in the 2023 TV schedule to cover some of the FBI's most high-stakes cases, with the agents who risked life and limb telling the story themselves in conversations with fellow former agents. The next episode on November 21 will examine the 2001 investigation into then-FBI agent Robert Hanssen, who is now known as the most damaging spy in the history of the Bureau for selling secrets to the Russians. Former FBI investigative specialist Eric O'Neill, who went undercover at Hanssen's side, spoke with CinemaBlend about his harrowing experience and the PTSD he suffered afterwards.
