U.S. Senator Richard Blumenthal asked the Department of Justice and the Financial Crimes Enforcement Network to explain their oversight of Binance following allegations tied to $1.7 billion in Iran-related sanctions evasion. The letter, sent on the 17th, raised concerns about the effectiveness of Binance’s external monitor and the strength of the exchange’s compliance controls. The inquiry continues to focus on sanctions compliance, enforcement follow-up, and whether Binance’s post-settlement supervision is adequately addressing reported Iran-linked activity.
