Federal Authorities Threaten Hennepin County Sheriff Dawanna Witt With Prosecution Over ICE Detainer Refusal

Hennepin County Sheriff Dawanna Witt disclosed that federal authorities have issued subpoenas and threatened her with criminal prosecution over the county jail’s policy of declining to hold people on civil ICE detainers absent a judicial warrant — a policy Hennepin County has maintained under state court precedent. This is an escalation of the federal campaign against sanctuary jurisdictions in Minnesota’s most populous county.

Witt has appeared before in this corpus’s Operation Metro Surge record, standing alongside Brooklyn Park’s police chief when he described ICE agents pretextually stopping off-duty officers of color (2026-01-20–bruley-brooklyn-park-officers-pretextual-ice-stops). A federal prosecution threat against a sitting county sheriff for refusing warrantless detainer compliance is a materially different order of escalation than the criminal charge Hennepin County itself brought against an ICE agent for assault during the same operation (hennepin-county-attorney-mary-moriarty-charges-ice-agent-gregory-donnell-morgan-jr-with-two-counts-of-second-degree-assault-first-state-criminal-charge-against-federal-immigration-agent-during-operation-metro-surge) — the federal government is now testing whether it can criminalize local law-enforcement non-cooperation directly, in the same county that prosecuted a federal agent. Whether DOJ follows through with charges will set a model other counties watch.
