A federal judge has invalidated subpoenas issued by the Department of Justice to Minnesota Governor Tim Walz and other state officials. The subpoenas were part of a DOJ investigation into the level of cooperation between Minnesota and federal immigration enforcement agencies. The judge’s decision effectively halts, at least temporarily, the federal government’s attempt to compel testimony from the state officials. Details of the judge’s reasoning were not immediately available, but the ruling represents a win for Walz and his administration, who had argued the subpoenas were overly broad and politically motivated. The DOJ initiated the probe amid concerns about Minnesota’s policies regarding sanctuary cities and assistance with federal immigration detentions. It remains unclear if the DOJ will appeal the judge’s decision or pursue alternative avenues to gather information.
