The Treasury’s payments system, the Office of Personnel Management (OPM) and General Services Administration (GSA) are among the major chokepoints DOGE has sought to take control of.\n\nThe case was brought against Mr Trump, the Department of the Treasury and Treasury Secretary Scott Bessent on Friday by Attorneys-General from 19 states.\n\nThe Attorneys-General alleged the administration violated the law by expanding access to sensitive Treasury data to staff from Mr Musk’s DOGE.\n\nProtesters against DOGE and Mr Musk outside the US Capitol earlier this week.
