Federal surveillance of protest movements has drawn renewed scrutiny as court fights test how far agencies can go in monitoring political activity. In Minnesota, newly disclosed filings in a federal case against anti-ICE protesters are shedding fresh light on how the Department of Homeland Security tracked meetings, churches and people tied to resistance during Operation Metro Surge. The records add detail to a broader dispute over undercover policing, electronic monitoring and the scope of evidence gathered during the federal immigration crackdown.
Court records describe undercover DHS monitoring tied to Operation Metro Surge
Court filings submitted August 25, 2026, in the federal prosecution of 15 Minnesotans include more than 200 pages of undercover agents’ notes and photographs from a Homeland Security surveillance operation, according to Minnesota Reformer and Truthout. The defendants have pleaded not guilty to conspiracy charges accusing them of assaulting, impeding or injuring federal officers during anti-ICE actions connected to Operation Metro Surge. Prosecutors have said they possess about 20 terabytes of data, though U.S. District Judge David Schultz previously indicated in court that not all of it appears tied directly to the charged defendants.
The newly described materials show agents documented meetings of anti-ICE groups, photographed vehicles associated with people who followed immigration agents, and gathered information at organizing spaces including churches, libraries and union venues, according to the filings cited by multiple outlets. Earlier filings in the same case also described administrative subpoenas for financial records linked to labor unions and advocacy organizations. Defense attorney Kevin Riach filed the exhibits as part of a broader push to compel additional disclosure about the surveillance campaign.
Reports on the filings also said agents used registrar and payment-processor records to identify people behind activist websites and employed software to capture Signal chat contents. The court record, as summarized by local and national coverage, names the surveillance efforts as Operation Puppet Master and Operation Whipple Shield. A hearing on defense requests for more records was scheduled for late August after the judge denied a government request to delay it, according to Truthout and Minnesota Reformer.
The filings place the heaviest confirmed impact in the Twin Cities, where agents were reported to have attended meetings at churches, a public library, parks, union spaces and other community sites. Religion News Service reported that court records indicate at least five churches in Minnesota and Michigan were surveilled, with activity occurring both outside and inside church buildings since December. In Minnesota, public reporting has specifically referenced churches in Minneapolis and Roseville as among the congregations drawn into the federal operation.
What is confirmed is that the filings describe surveillance at religious and community gatherings during the immigration enforcement surge that began in winter 2025 and continued into early 2026. What is not yet publicly known is the full number of worshippers, organizers or meeting attendees whose information was logged, photographed or retained by federal investigators. The government also has not released a comprehensive public list of every Minnesota location or every individual whose vehicle or presence was documented in the operation.
The records have also raised questions about whether any surveillance intersected with protected religious activity or with prior court limits on immigration enforcement at houses of worship, an issue highlighted in subsequent reporting. Minnesota Attorney General Keith Ellison publicly criticized the undercover activity after the first round of filings became public, according to FOX 9. Those questions are likely to remain part of the ongoing court fight as judges review the scope and legality of the evidence collection.
According to the court filings summarized by Minnesota Reformer and other outlets, the surveillance grew out of the federal government’s response to organized resistance during Operation Metro Surge, a large immigration enforcement initiative in Minnesota. Reports describe Homeland Security using undercover agents, electronic monitoring, vehicle tracking, chat collection and administrative subpoenas to map networks of protest groups, labor organizations and allied institutions. The records presented to grand jurors included diagrams linking numerous organizations under a theory of conspiracy, according to public reporting on the filings.
For Minnesota residents, the immediate consequence is not a new public enforcement announcement but a clearer picture of how extensively community spaces were monitored during the operation. The case does not yet provide a final court ruling on whether the surveillance methods were lawful, and no public filing has fully accounted for how much of the collected material will be used at trial. The practical next step is further litigation over disclosure, suppression and the permissible scope of the government’s evidence.
The federal prosecution of the 15 defendants is still pending, and the surveillance dispute is unfolding through motions and hearings rather than a final judgment. That means residents and congregations referenced in the filings may continue to learn new details as additional exhibits are filed or unsealed. For now, the most established fact is that court records have documented a broad DHS intelligence operation that reached far beyond street protests and into churches and neighborhood meeting spaces in Minnesota.
