MINNEAPOLIMEDIA NEWS | Federal Officials Threatened Hennepin County Sheriff With Prosecution Over ICE Access

Hennepin County Sheriff Dawanna Witt says federal officials threatened her with possible witness-tampering charges because her office would not grant immigration agents the broader jail access they requested. Witt maintains that the Sheriff’s Office is following Minnesota law and constitutional requirements.

MINNEAPOLIS, MN (August 6, 2026) Federal officials threatened Hennepin County Sheriff Dawanna Witt with possible criminal prosecution amid a continuing dispute over access by immigration agents to people held in the Hennepin County Jail, according to Witt and local news reports.

Witt said federal representatives hand-delivered a letter in early July warning that she could face a federal witness-tampering investigation or prosecution because her office had not provided U.S. Immigration and Customs Enforcement with the level of access it sought.

No criminal charge had been filed against Witt as of Thursday, August 6.

The sheriff said the federal government’s warning would not cause her office to disregard state law, constitutional protections or existing jail policies.

Dispute Centers on Access to People in Custody

Federal immigration officials have sought greater access to people held in county jails, particularly those whom ICE believes may be subject to immigration enforcement.

Witt’s position is that the Hennepin County Sheriff’s Office cooperates when presented with legally sufficient authority, including valid judicial warrants, but cannot hold people beyond the time they would otherwise be released solely because of a civil immigration detainer.

An ICE detainer is a request asking a local jail to notify federal immigration authorities before a person is released and, in some cases, to continue holding that person temporarily. It is not the same as a criminal warrant signed by a judge.

Minnesota Attorney General Keith Ellison has previously advised that state and local law-enforcement agencies generally may not continue detaining someone solely on the basis of an immigration detainer after that person would otherwise be entitled to release.

A 2019 Minnesota Court of Appeals decision also found that continuing to hold an individual under those circumstances could violate state law and constitutional protections.

Witt Rejects Witness-Tampering Allegation

Witness tampering ordinarily involves attempting to improperly influence, intimidate or interfere with a witness in an official proceeding or investigation.

Witt has denied that her office engaged in any such conduct. She contends that the disagreement involves jail access and the limits of local authority, not interference with a witness.

The sheriff said federal officials have not identified a legal basis that would require her to provide unrestricted access to people in county custody.

Her position does not mean that federal authorities are prohibited from enforcing immigration law. Rather, the dispute concerns whether local officials can be compelled to participate in enforcement activities beyond what state law permits.

Federal Pressure on Local Law Enforcement

The warning represents an escalation in the conflict between federal immigration authorities and Minnesota officials over the role of counties and cities in immigration enforcement.

Federal officials have repeatedly criticized jurisdictions that limit voluntary cooperation with ICE. Local officials have responded that they must comply with the Constitution, Minnesota law and court decisions governing detention and access to people in custody.

The dispute also carries public-safety implications. Some local officials and immigrant advocates argue that extensive cooperation with federal immigration authorities can discourage crime victims and witnesses from contacting police.

Federal officials, meanwhile, argue that access to people already in custody allows immigration arrests to occur in controlled environments rather than in homes, workplaces or public spaces.

No Charges Have Been Filed

The federal letter constitutes a threat of possible investigation or prosecution, not a criminal charge or a finding that Witt violated the law.

No court has determined that the sheriff committed witness tampering, and the federal government would need to establish the required legal elements before any criminal liability could be imposed.

Witt said she intends to continue carrying out her responsibilities under the law despite the warning.

The Hennepin County Sheriff’s Office operates the county jail and provides law-enforcement services across Minnesota’s most populous county. Any federal prosecution of its elected sheriff over an immigration-enforcement dispute would carry significant legal and political consequences.
