Hennepin County Sheriff outlines limits on ICE cooperation as federal enforcement escalates in Minnesota

What the sheriff’s office says it will—and will not—do

The Hennepin County Sheriff’s Office is drawing a bright line between cooperation on criminal investigations and participation in civil immigration enforcement, as federal immigration activity and public attention remain elevated across Minnesota.

In a public-facing explanation of its policies, the sheriff’s office states that it works with local, state and federal partners on criminal investigations and enforcement of criminal laws, but does not assist with civil immigration enforcement. The office also states that its deputies do not ask about immigration status and that the agency does not track immigration status.

Inside the Hennepin County Jail, the sheriff’s office says it will not honor administrative detainers or administrative warrants, describing those documents as not being criminal warrants signed by a judge. The stated policy is that the jail will comply only when presented with a judicially signed warrant.

Why the distinction matters inside the county jail

The practical impact of these policies is most visible at the jail, where release decisions must align with criminal court orders and constitutional requirements. Detainer requests connected to civil immigration enforcement have been a recurring point of contention nationally, because they can involve holding someone beyond a scheduled release without a judicial warrant.

Hennepin County’s stance is not new. In 2014, the county moved away from honoring immigration detainers that requested extended custody after a person would otherwise be released. More recently, the sheriff’s office has reiterated that it will not extend detention time based on administrative detainers, while still complying with judicial warrants.

How the sheriff’s office describes its role during ICE operations and protests

The sheriff’s office says its deputies lack authority to stop other law enforcement agencies from carrying out their duties, including civil immigration enforcement by federal agents. The office adds that it will respond to emergency calls within its jurisdiction and will respond to scenes that could become violent.

In courthouses, the sheriff’s office says deputies may be present because state law mandates court security and requires the sheriff to “keep and preserve the peace of the county.” The sheriff’s office says its presence in shared public spaces should not be interpreted as directing federal agents’ actions.

• The sheriff’s office says it cooperates with federal agencies on criminal matters.
• It says it does not assist with civil immigration enforcement.
• It says the jail will not honor administrative detainers or administrative warrants, and will comply only with judicially signed warrants.

Ongoing friction over reports of non-cooperation

Past disputes illustrate how disagreements can flare even when local officials say they are following established policy. In 2017, after federal authorities issued a report alleging that detainees were released before ICE could take custody, Hennepin County officials publicly disputed the accuracy of the claims and said the individuals were transferred to ICE custody at the time of release.

The central question remains consistent: whether federal immigration enforcement requests are backed by a judicial warrant, and whether local custody can be extended without one.

The sheriff’s office position frames its approach as compliance with judicial orders and criminal-law responsibilities, without taking on the civil immigration enforcement role reserved to federal authorities.
