According to reports cited in the new update, three U.S. Democratic senators said they will oversee the Justice Department’s reported investigation into whether Binance was used to violate Iran-related sanctions. The Wall Street Journal said the DOJ is examining whether Iran used Binance to evade sanctions. Binance said it is unaware of any investigation, while adding that it is cooperating with regulators and law enforcement. The development adds congressional oversight and Binance’s public response to earlier reporting that the DOJ was investigating alleged Iran-linked crypto transactions involving the exchange.
