Mel Weinberg was an infamous con artist and informant who played a key role in the FBI's ABSCAM sting operation during the late 1970s and early 1980s. He orchestrated elaborate scams and schemes, often targeting wealthy individuals and politicians, which led to numerous convictions. Weinberg's involvement in ABSCAM resulted in the indictment and conviction of several congressmen and public officials for bribery and corruption. His story inspired the 2013 film "American Hustle," where he was portrayed by Christian Bale.
