Federal prosecutors opened a criminal investigation in early 2026 into Governor Tim Walz and Minnesota officials over potential obstruction of ICE enforcement tied to sanctuary policies, while separate federal and state probes into widespread Medicaid and housing fraud have yielded indictments against numerous individuals but none against Walz personally. Congressional oversight hearings examined allegations of prior knowledge and inadequate oversight of the fraud schemes, which estimates placed in the billions. As of June 2026, no indictment has been announced, leaving the December 31, 2026 resolution dependent on whether investigators obtain sufficient evidence for formal charges. Walz, who announced he would not seek a third term, faces continued scrutiny from federal agencies amid these parallel inquiries.
