On October 23rd, 2025, President Donald Trump pardoned convicted founder of Binance Changpeng Zhao. Janet Yellen, former Treasury Secretary said of CZ and Binance, "Binance turned a blind eye to its legal obligations in the pursuit of profit… Its willful failures allowed money to flow to terrorists, cybercriminals, and child abusers through its platform."
