Andriesz spent nine years as a whistleblower, providing the FBI and House Oversight Committee with 2018 emails linking Lutnick to Jeffrey Epstein's Adfin investment. His evidence led to a £96m tax assessment from HMRC and a $3 million CFTC fine against BGC in 2019. BGC has called these accusations categorically false, and Lutnick denies any business relationship with Epstein, despite acknowledging a visit to Epstein's island. Separate UK court proceedings found that BGC personnel stole £23.5 million from tax authorities between 2015 and 2020.
