Sixteen US lawmakers have written to President Joe Biden, urging him to intervene in the case of Tigran Gambaryan, a Binance executive who has been detained in Nigeria for three months. Gambaryan, a former IRS agent, was arrested in February and charged with money laundering and tax evasion. Despite the Nigerian government dropping the tax evasion charges, Gambaryan remains in custody.

The lawmakers are concerned about Gambaryan's health, which has deteriorated significantly since his arrest. He has contracted malaria and double pneumonia, and his family has expressed worry about his well-being. The lawmakers are calling for his immediate humanitarian release, citing the poor prison conditions and his health state.

During a recent visit to the Kuje Prison in Nigeria, lawmakers Chrissy Houlahan and French Hill met with Gambaryan and expressed their concerns about his situation. They emphasized the importance of prompt action, highlighting Gambaryan's cooperation with Nigerian authorities and his struggle against financial crimes.

The case has sparked diplomatic tensions between the US and Nigeria, with many former federal prosecutors and agents joining the call for Gambaryan's release. The next trial session is set for July 9, 2024, but the lawmakers are urging the US government to take immediate action to secure Gambaryan's release.

Gambaryan's wife, Yuki, has criticized the US government for its delayed response, urging more decisive action to secure her husband's release. The situation highlights the complexities of international diplomacy and the importance of protecting the rights of US citizens abroad.
