Wu said that according to Fox reporter Eleanor Terrett, 12 American politicians wrote to US President Biden, Secretary of State Antony Blinken and Presidential Envoy for Hostage Affairs Roger D. Carstens on June 4, urging the US government to take immediate action to ensure the safety and protection of Tigran Gambaryan, an American citizen and Binance Financial Crime Compliance Director who was illegally detained by the Nigerian government. The letter stated that the Nigerian government charged him with multiple crimes and transferred him to the notorious Kuji Prison; Gambaryan experienced excessive and harsh treatment during detention, contracted malaria, and failed to ensure that he received adequate medical care.
