Senator Richard Blumenthal (Democrat from Connecticut) has sent letters to the U.S. Justice Department and Treasury, demanding answers about Binance's compliance monitors after $1.7 billion was reportedly funneled through the exchange to wallets linked to Iran. This inquiry follows Binance's guilty plea in November 2023 for failing to register as a money transmitting business and breaching sanctions, resulting in over $4 billion in penalties and a requirement to retain an independent compliance monitor for three years. Blumenthal expressed concern over allegations of inadequate anti-money laundering measures by Binance, highlighting that internal investigators were reportedly fired for raising alarms about the Iranian transactions. He has requested details regarding the monitor's status and any misconduct reports by April 24. The scrutiny comes amid reports that Binance facilitated significant sanctions evasion for Iranian entities, raising questions about the company's adherence to its settlement terms from 2023.
