Nine United States Senate Democrats have formally asked the Treasury Department and the Department of Justice to investigate Binance’s compliance with anti money laundering and sanctions rules, escalating political pressure on the world’s largest cryptocurrency exchange.
In a letter sent to Treasury Secretary Scott Bessent and Attorney General Pam Bondi, the lawmakers raised concerns about recent media reports suggesting potential illicit finance breaches involving the platform. The senators cited allegations that funds may have been channeled through Binance to entities linked to terrorist organizations or sanctions evasion.
The letter argues that such claims, if verified, would indicate significant weaknesses in the exchange’s illicit finance controls. The lawmakers requested that federal agencies assess whether Binance remains in compliance with obligations stemming from its 2023 settlement with US authorities, which required the company to strengthen its anti money laundering and know your customer frameworks.
Among the signatories were Senators Elizabeth Warren, Richard Blumenthal, Mark Warner, Ruben Gallego and Angela Alsobrooks, along with four other Democratic lawmakers. Several of them have been directly involved in negotiations over the Digital Asset Market Clarity Act, a bill intended to establish a comprehensive regulatory structure for US crypto markets.
Senator Blumenthal, a senior member of the Senate Homeland Security Committee, had earlier announced his own inquiry into Binance and sent a separate request for information to the company. However, Democrats are currently not in the majority in the Senate, limiting their authority to initiate formal committee investigations without bipartisan support.
The letter states that allegations of weak compliance controls raise serious national security concerns. Lawmakers emphasized that the integrity of US illicit finance enforcement could be undermined if large sums were allowed to flow through crypto platforms to sanctioned actors or extremist groups.
Binance co chief executive Richard Teng has previously described certain media reports on the matter as inaccurate and defamatory. The company has not issued a detailed public response to the latest request from senators. Binance has maintained that it has significantly enhanced its compliance systems in recent years and invested heavily in transaction monitoring and regulatory cooperation.
The renewed scrutiny comes at a sensitive moment for US crypto legislation. Illicit finance prevention remains one of the most contested elements of the Digital Asset Market Clarity Act. Lawmakers continue to debate how to balance innovation with stronger oversight of exchanges and digital asset intermediaries.
The senators’ letter also referenced broader political concerns surrounding the crypto sector, including previous ties between Binance and entities connected to high profile political figures. These references further complicate legislative negotiations, as policymakers weigh market structure reforms alongside enforcement and conflict of interest questions.
