According to Bloomberg, several Democratic senators from the United States have written to the Secretary of the Treasury and the Attorney General, asking for clarification on whether the cryptocurrency exchange Binance has any connections to the Trump family, especially after its stablecoin USD1 was used to fund Abu Dhabi's $2 billion investment in Binance. The senators are concerned that the exchange may continue to operate in the U.S. after pleading guilty and are requesting responses by May 21 regarding Binance's compliance with regulations and whether the Trump family is seeking a pardon for Zhao Changpeng.
