Chicago-Area Cops Helped HSI Spy on Minnesota Anti-ICE Activists

The revelation stems from a newly disclosed April 2026 report authored by Homeland Security Investigations (HSI), a division of ICE, titled Antifa Roadshow. The document exposes a sophisticated, multi-jurisdictional surveillance effort targeting an April 2 speaking engagement at the Co-Prosperity gallery in the Bridgeport neighborhood of Chicago. The event served as a stop on a national speaking tour organized by the anarchist collective Crimethinc, intended to discuss resistance strategies employed during a contentious three-month immigration surge in the Twin Cities—a period marked by the fatal shootings of two US citizens.

The surveillance operation involved a 14-member joint task force comprised of eight HSI Chicago agents and six officers from local municipal departments, including Aurora, Downers Grove, and law enforcement representatives from Cook and Kane counties. This cooperation highlights the intersection of local police resources and federal investigative mandates, a partnership that has drawn sharp criticism from civil liberties advocates who characterize the activity as a form of ideological policing.

The Anatomy of the Surveillance Operation

The investigative report details a granular, high-tech approach to monitoring political dissent. Utilizing a combination of undercover operatives, electronic surveillance, and the integration of Chicago’s extensive CCTV network, the task force sought to map the connections between Chicago-based activists and the Minnesota 15—a group of activists currently facing federal felony charges.

The operation began with logistical reconnaissance. A plainclothes officer from the Aurora Police Department was positioned at the venue after being transported by an officer from the Downers Grove Police Department. Once the Aurora officer confirmed the absence of security screening measures at the venue’s entrance, HSI undercover agent #9147 entered the gallery. For approximately one hour, the agent transmitted live audio recordings of the proceedings to the task force until technical difficulties interrupted the feed.

The data gathered during this period was extensive. The HSI team logged 219 license plates of vehicles parked in the vicinity of the Bridgeport gallery. By cross-referencing this data with regional databases and surveillance cameras, agents identified multiple attendees already under investigation for their participation in previous anti-ICE demonstrations, including protests at the Broadview Detention Center. One specific entry in the report details a Kane County Sheriff’s deputy identifying a masked individual through a license plate check, linking him to a previous arrest during the autumn 2025 Operation Midway Blitz.

Chronology of Federal Oversight and Enforcement

The monitoring of the Bridgeport event was not an isolated incident but part of a broader, coordinated strategy to track the Crimethinc speaking tour across the United States. Discovery documents released by the defense team for the Minnesota 15 indicate that HSI agents similarly infiltrated and monitored tour events in Ann Arbor, Michigan, and Seattle, Washington.

The timeline of this investigation runs parallel to the intensifying legal pressure on the Minnesota 15. The federal case, which alleges a conspiracy to resist immigration enforcement, has relied heavily on the documentation of speech and organizing tactics. The HSI report explicitly notes that remarks made by defendant Callum Robinet during the April 2 event—specifically regarding the creation of rapid-response networks—were transcribed and incorporated into the federal indictment.

The use of federal agents to monitor political speech marks a significant shift in the operational focus of HSI. Traditionally tasked with investigating transnational crime, human trafficking, and immigration violations, the agency has increasingly become the primary vehicle for federal investigations into domestic political dissent. This shift is underscored by the agency’s recent role in serving a search warrant on the office of Representative Ilhan Omar, a move that has further fueled concerns regarding the politicization of the department.

The Legal Framework of Task Force Cooperation

A central point of contention remains the role of local law enforcement in federal operations that target political activity. Illinois state law contains specific prohibitions against local police departments participating in direct immigration enforcement. However, the Chicago Police Department (CPD) and participating suburban agencies have maintained that their cooperation with HSI in this instance was permissible because it was framed as a criminal investigation rather than an immigration-specific enforcement action.

According to internal sources, the CPD justified the surveillance as part of a federal racketeering investigation. Despite this, the primary evidence of "financial crime" mentioned in the report is a public GoFundMe campaign used to support the speaking tour. There is no evidence in the document suggesting that funds were solicited or illegally obtained at the April 2 event.

Furthermore, the CPD’s internal policies require specific procedural steps for the surveillance of public gatherings. A 2017 departmental order dictates that any infiltration of a political event must be authorized through the department’s chain of command and reviewed by general counsel. In response to inquiries, the CPD stated that no First Amendment notifications were filed for the April 2 operation, raising questions about whether federal task force participation serves as a loophole to bypass local oversight mechanisms.

Reactions and Broader Implications

The disclosure has elicited a sharp response from the American Civil Liberties Union (ACLU) of Illinois. Ed Yohnka, a spokesman for the organization, described the monitoring as "very troubling" and called for a transparent accounting of why municipal resources were deployed to surveil individuals engaged in constitutionally protected political expression.

"No one should be subjected to surveillance and infiltration by law enforcement simply for engaging in constitutionally protected activity, including the ability to gather together and express dissatisfaction with public policy," Yohnka stated. He further urged local agencies to reconsider their participation in federal task forces, particularly those that appear to prioritize the monitoring of domestic dissent under the guise of national security.

The lack of transparency from the involved agencies—including the Aurora and Downers Grove police departments, as well as the Kane County Sheriff’s office—has left a vacuum of accountability. ICE has declined to comment on the specifics of the investigation, citing internal policy that prohibits agents from speaking to the media regarding active or past cases.

Analysis: The Cost of Inter-Agency Integration

The integration of local law enforcement into federal task forces creates a complex web of liability and responsibility. By pooling resources, local police gain access to federal funding and technology, but they also effectively surrender operational control to agencies whose priorities may diverge from local community standards.

The "Antifa Roadshow" report serves as a case study in the blurring of these lines. By utilizing local street-level officers and license-plate-reader data to assist a federal agency in monitoring a political speaking tour, local police have positioned themselves as active participants in the federal prosecution of activists. This creates a scenario where a resident’s participation in a local town hall or a peaceful lecture could result in them being flagged in a federal database, regardless of whether they have committed a crime.

As the federal government continues to leverage HSI for investigations into political networks, the role of local agencies in these task forces will likely face increasing scrutiny from city councils and state legislatures. For residents in the Chicago area, the Bridgeport incident serves as a stark reminder of the reach of domestic surveillance and the ongoing debate regarding the extent to which local police should assist in federal efforts to monitor domestic political speech. The ongoing trial of the Minnesota 15 will continue to serve as the legal testing ground for the evidence gathered during these operations, potentially setting a precedent for how future political dissent is categorized and handled by federal and local law enforcement partnerships.
