Eleven Democratic senators on the U.S. Senate Banking, Housing, and Urban Affairs Committee have collectively pressed the Trump administration to launch a comprehensive investigation into Binance. This call for action stems from serious allegations that the digital asset exchange facilitated illicit finance activities, particularly those linked to Iran, and may be in violation of its 2023 federal settlement agreement.

In a letter dispatched on Friday to Attorney General Pam Bondi and Treasury Secretary Scott Bessent, the lawmakers urged the Justice Department and Treasury to conduct a “prompt, comprehensive review” of Binance’s sanctions compliance controls. They highlighted recent media reports that indicated billions of dollars in digital assets allegedly flowed through the Binance platform to various Iranian entities, including groups with suspected ties to terrorism.

The letter was spearheaded by Senator Mark Warner and co-signed by Ranking Member Elizabeth Warren, along with Senators Chris Van Hollen, Jack Reed, Catherine Cortez Masto, Tina Smith, Raphael Warnock, Andy Kim, Ruben Gallego, Lisa Blunt Rochester, and Angela Alsobrooks. The senators specifically cited evidence allegedly uncovered by Binance compliance personnel last year, revealing that approximately $1.7 billion in digital assets had been routed through the exchange to Iranian entities, notably including the Iran-backed Houthis and the Islamic Revolutionary Guard Corps. Further claims in the letter included an instance where a Binance vendor purportedly moved $1.2 billion in funds connected to Iran-linked actors, and that over 1,500 Iranian user accounts had accessed the platform. Concerns were also raised about the platform's potential use by Russian actors for sanctions evasion.

Adding to these worries, the lawmakers expressed apprehension that employees who initially identified these transactions were subsequently dismissed, and that Binance has shown decreased responsiveness to law enforcement requests. They argued that such actions would directly contradict the company’s obligations outlined in its 2023 plea agreement and associated settlements. In 2023, Binance pleaded guilty to federal charges, including violations of U.S. sanctions laws and failures in anti-money laundering protocols. As part of this agreement, the company consented to pay over $4 billion in penalties and committed to implementing extensive reforms under U.S. supervision, which included enhanced know-your-customer procedures and robust sanctions screening. The senators' letter contends that the latest reports cast doubt on whether these critical reforms have been effectively implemented and sustained. Specifically, the letter noted that allowing $1.7 billion in digital assets to reach sanctioned Iranian entities would be inconsistent with Binance's commitment to the Treasury’s Office of Foreign Assets Control (OFAC) to establish controls capable of identifying and blocking prohibited transactions.

The letter also delved into Binance’s recent business dealings involving former President Donald Trump and his family’s cryptocurrency ventures. Lawmakers pointed to Binance's promotion of USD1, a stablecoin issued by World Liberty Financial, a project supported by the Trump family. Allegations included Binance offering interest incentives for USD1 holders, providing technological assistance for the token, and accepting a $2 billion investment tied to it. Furthermore, the senators referenced Trump’s pardon of Binance founder Changpeng Zhao last fall, who had pleaded guilty to failing to implement an effective anti-money laundering program and served a four-month prison sentence. The lawmakers asserted that these connections amplify the necessity for what they described as a
