Three Democratic senators say they will oversee a reported Justice Department investigation involving crypto exchange Binance. Lawmakers want to ensure authorities review possible sanctions violations linked to Iran. The request follows a report indicating Iranian entities may have used the platform to bypass restrictions. The move signals renewed scrutiny toward the world’s largest cryptocurrency exchange.
Senators Chris Van Hollen, Elizabeth Warren, and Ruben Gallego issued a joint statement on Thursday. They said they will monitor the Justice Department’s actions closely. The senators aim to confirm that investigators pursue the case seriously. They also stressed that authorities must hold the company accountable if violations occurred.
The development follows a report published by the Wall Street Journal. The report cited sources familiar with the situation. According to the publication, the Justice Department is examining whether Iranian actors used Binance to evade US sanctions. The alleged activity could involve entities connected to Iran’s government and affiliated groups.
The lawmakers argued that the exchange has previously prioritized growth over regulatory compliance. They also raised concerns about earlier enforcement actions involving the platform. Additionally, they warned that sanctions violations could indirectly support groups connected to Iran.
The senators recently contacted senior US officials about the issue. Last month, they wrote to Treasury Secretary Scott Bessent and Attorney General Pam Bondi. Their request asked both officials to investigate concerns involving Iran-linked transactions. Lawmakers believe authorities must examine how such funds could move through global crypto platforms.
Meanwhile, the Justice Department has not publicly confirmed the reported investigation. However political pressure around crypto compliance continues to grow. Several lawmakers are arguing that digital asset platforms must strengthen monitoring tools. They also want stronger enforcement of sanctions compliance across the industry.
At the same time, Binance said it was unaware of any investigation. The exchange stated that it is working with authorities to review facts whenever concerns arise. The company has also maintained that it follows applicable compliance standards.
Binance also launched legal action against the Wall Street Journal this week. The company filed a defamation lawsuit linked to a previous report published in February. That article alleged the exchange dismissed employees who flagged suspicious transactions tied to sanctioned Iranian entities.
The report claimed those transactions involved roughly one billion dollars in crypto activity. The entities allegedly included groups linked to Yemen’s Houthis and Iran’s Islamic Revolutionary Guard Corps. Binance denied the allegations and said it never halted internal investigations related to the activity.
The exchange argued that the report contained inaccurate information about its compliance procedures. Consequently the lawsuit seeks to challenge claims made in the article. The legal action adds another layer to the ongoing dispute between the company and the newspaper.
The current concerns arrive after Binance already faced major US enforcement action. In November 2023, the company pleaded guilty to violating anti-money-laundering and sanctions laws. Binance agreed to pay a record four point three billion dollar settlement. The exchange also accepted years of monitoring under US oversight.
Former Binance chief executive Changpeng Zhao also faced criminal charges. He pleaded guilty to a money-laundering related offense connected to the investigation. Authorities later sentenced him to four months in prison during 2024. In October, US President Donald Trump granted Zhao a presidential pardon.
