Democratic senators are calling on federal authorities to investigate Binance over potential Iran sanctions breaches.
On February 27, 2026, eleven members of the Senate Banking Committee sent a formal letter to Treasury Secretary Scott Bessent and Attorney General Pam Bondi.
The lawmakers cited recent reports of alleged illicit financial activity on the exchange. They warned that national security could be at risk if Binance is once again flouting U.S. sanctions law.
Senators Cite Evidence of $1.7 Billion Flowing to Iranian Entities
The letter detailed troubling findings uncovered by Binance’s own compliance personnel last year. According to the senators, staff discovered that $1.7 billion in digital assets had flowed to Iranian-linked entities.
Those entities reportedly include the Iran-backed Houthis and the Islamic Revolutionary Guard Corps. In one instance, a Binance vendor allegedly directed $1.2 billion in funds toward Iran-linked accounts.
The senators opened their letter with a direct call to action. “We urge you to conduct a prompt, comprehensive review of sanctions compliance on the platform to ensure that it is not once again violating the law and threatening U.S. national security,” they wrote.
The senators also noted that Iranians had reportedly accessed more than 1,500 accounts on the platform. There were further indications the exchange may have been used to help Russia evade U.S. sanctions as well.
These findings led the Democratic senators to question whether Binance is honoring the terms of its 2023 settlement.
That agreement followed Binance’s guilty plea on charges that included money laundering and sanctions violations.
Making matters worse, Binance reportedly fired the compliance staff who uncovered the Iranian transactions. The senators called this a potential act of retaliation against employees performing their duties.
The Democratic senators argued that these developments point to a broad breakdown in compliance at Binance. Under its 2023 agreements, Binance committed to controls that would “enable it to clearly and effectively identify and interdict transactions and activity that may be prohibited by OFAC.”
Senators said the alleged $1.7 billion in illicit flows suggests those controls are not functioning. Law enforcement sources also reportedly said Binance has grown less cooperative with information requests.
Democratic Senators Flag Trump Family Ties as Conflict of Interest
Beyond the sanctions concerns, the Democratic senators raised a separate but related issue. They pointed to deepening financial ties between Binance and President Trump’s family as a potential conflict.
The exchange has repeatedly promoted USD1, the stablecoin launched by the Trump family’s World Liberty Financial. Binance also helped develop the technology behind USD1 and accepted a $2 billion investment in the token.
The senators were direct in addressing those ties. “We recognize, of course, that Binance has made numerous business decisions that have helped President Trump and his family profit from their crypto ventures,” they wrote.
They also referenced Trump’s pardon of Changpeng Zhao, Binance’s founder and former chief executive. Zhao had pleaded guilty to failing to establish an effective anti-money laundering program before receiving the presidential pardon.
The senators stressed that the stakes extend beyond politics. “If Binance has begun to ignore its illicit finance obligations, the risks are grave and nonpartisan,” they stated in the letter.
Ranking Member Elizabeth Warren led the effort alongside ten Democratic colleagues on the Banking Committee. The group set a deadline of March 13, 2026, for a formal response outlining steps taken to address their concerns.
