Democratic lawmakers are calling for a Treasury Department investigation into the access granted to Elon Musk’s team regarding the government’s payment systems, citing concerns over economic threats, national security, and potential privacy violations. In letters to Treasury officials, including Secretary Scott Bessent, they expressed worries about transparency and accountability, particularly regarding the review's legality and its implications for critical payments like Social Security. Labor unions and advocacy groups have also filed lawsuits to halt the review, which has been restricted to two workers following a judge's order.
