DOGE, led by Elon Musk, is reportedly targeting a $1 trillion reduction in federal spending. Unnamed sources told the Journal representatives of DOGE have been on-site at CMS' offices, searching for fraud or waste, and examining the agency's organization and staffing.

Two senior agency veterans focused on policy and operations are working with DOGE to review the agency overseeing Medicare and Medicaid, which provide health insurance for about 1 in 4 Americans, according to a U.S. Department of Health and Human Services spokesman.
