The regulatory heat surrounding Binance, the world’s largest cryptocurrency exchange, has intensified once again. US Senator Richard Blumenthal (D-CT) has officially called for an update on the company’s court-mandated monitoring program, citing serious concerns over potential lapses in anti-money laundering (AML) protocols and ties to sanctioned entities in Iran.
This inquiry follows a high-stakes 2023 settlement where Binance agreed to pay $4.3 billion to resolve federal charges, and its founder, Changpeng “CZ” Zhao, pleaded guilty to a felony charge. As part of that deal, the exchange was placed under the strict supervision of the Department of Justice (DOJ) and the Treasury’s Financial Crimes Enforcement Network (FinCEN).
Blumenthal Questions “Dangerously Lax” Oversight
Senator Blumenthal’s recent letters to the DOJ and FinCEN express a growing skepticism regarding Binance’s commitment to its legal obligations. The Senator highlighted “mounting allegations of dangerously lax anti-money laundering prevention,” questioning whether the exchange is truly adhering to the terms set during its 2023 settlement.
The pressure isn’t just coming from Blumenthal. Earlier this year, a bipartisan group of lawmakers, including Senator Chris Van Hollen, urged the Treasury and the Attorney General to conduct a “prompt, comprehensive review” of the exchange’s internal controls. Despite these inquiries, officials from the DOJ and FinCEN have remained tight-lipped, declining to comment on the active monitoring process.
Allegations of Iran Sanction Evasions and Political Ties
The core of the current controversy stems from reports that Binance may have facilitated nearly $1 billion in transactions linked to Iranian entities. Internal whistleblowers allegedly flagged these flows to executives, only to be fired shortly after. While Binance spokespeople have denied these claims, the optics have fueled a firestorm in Washington, particularly regarding the exchange’s influence on US soil.
Adding a layer of political complexity are the ties between Binance and the current administration. In late 2025, former CEO CZ was granted a presidential pardon after serving a four-month prison sentence. Furthermore, reports surfaced in March 2025 regarding a $2 billion stake in Binance purchased by a UAE-based entity using USD1, a stablecoin issued by World Liberty Financial—a company co-founded by the Trump family.
These overlapping financial and political interests have led several lawmakers to allege a conflict of interest. They argue that the administration’s proximity to the crypto industry may be softening the regulatory oversight that was originally designed to prevent Binance from becoming a conduit for illicit finance. As the monitor’s report remains under wraps, the demand for transparency continues to grow on Capitol Hill.
