Asked about the investigation, the Department of Education referred ABC News to an appeals court decision last month, which did allow DOGE access to sensitive data at several agencies, including the student loan portfolio at the department. The acting inspector general said it “plans to look into the Department’s processes for managing access to several sensitive Department data systems.” This will be a coordinated effort with the Government Accountability Office, which is also looking into issues involving access and handling of sensitive data at the department, according to the letter from the acting inspector general. A fierce advocate of public education, Warren has vowed to fight the administration’s federal education-reduction efforts at every turn.
