Democratic members of the U.S. Senate demand urgent clarifications from the Treasury and Justice Departments regarding the legal obligations of the "Binance" platform following previous accusations of violating anti-money laundering laws and sanctions. The letter warns of secret meetings between platform officials and the government, and raises concerns about potential easing of oversight and connections to Trump's cryptocurrency project via the "USD1" coin. These actions come amid reports of "Binance" communicating with foreign companies despite its commitment to exit the U.S. market under a judicial settlement in 2023, sparking controversy among supporters of increased regulation and advocates of technological innovation.
