Democratic Senators Chris Van Hollen, Elizabeth Warren, and Ruben Gallego have pledged to oversee a reported Department of Justice investigation into Binance for potential Iran-related sanctions violations. The senators emphasized their commitment to ensuring a thorough investigation and holding Binance accountable for any misconduct. This follows a Wall Street Journal report suggesting the DOJ is examining whether Iran used Binance to circumvent sanctions. The senators expressed concerns over Binance's alleged history of prioritizing profits over legal compliance, particularly in relation to US sanctions laws. Binance has denied awareness of any ongoing investigations but stated its cooperation with regulators. The company recently filed a defamation lawsuit against the Wall Street Journal, disputing claims that it dismissed employees who reported suspicious transactions linked to sanctioned Iranian entities.
