Senior Democrats are demanding investigations into Elon Musk's DOGE after concerns of unauthorized access to sensitive government data at agencies like OPM and USAID. A letter emphasizes the illegality of Musk's access and calls for deputy inspectors general to probe potential national security breaches. Recent legal disputes have temporarily limited DOGE's access to the Treasury Department’s payment system. Public polling shows diminished Republican support for Musk's influence in government, and lawsuits challenge DOGE’s operations across multiple agencies, reflecting growing bipartisan unease over its activities.
