The Treasury Department's Office of Inspector General is conducting an audit of the federal government's payment system security controls following concerns raised by Democratic senators about access granted to Elon Musk's Department of Government Efficiency team. The audit will review two years of transactions and alleged fraudulent payments. Democratic lawmakers and federal employee unions are seeking transparency and accountability regarding Musk's team's activities. Musk's claims of finding waste, fraud, and abuse have not been substantiated, raising concerns about potential risks to government computer systems and private information. The Treasury Department provided conflicting information about DOGE's access to the payment system, leading to calls for a clear and public accounting of the situation.
