Federal agents conducted secret surveillance of progressive activists, labor unions, and protesters in Minneapolis during immigration enforcement operations under the Trump administration, according to court documents filed Thursday in federal court.
The 26-page motion reveals two operations—”Operation Puppet Master” and “Project Whipple Shield”—that officials claimed were designed to track potential threats during immigration crackdowns. The surveillance targeted groups organizing protests and advocating for immigrant rights in the Minneapolis area.
Who Was Monitored and Why
The court filing describes how Department of Homeland Security agents tracked communications, movements, and activities of groups opposing federal immigration enforcement. Officials justified the surveillance as necessary to identify security threats and coordinate responses to demonstrations.
The operations came during heightened immigration enforcement in Minneapolis, when federal agents conducted workplace raids and deportation sweeps that drew large public protests. The surveillance appears to have focused on groups mobilizing opposition to these enforcement actions rather than on individuals suspected of criminal activity.
Legal Questions About Domestic Monitoring
The disclosure raises questions about the scope of federal surveillance powers and when monitoring of political activity crosses constitutional lines. Civil liberties advocates argue the operations targeted Americans exercising First Amendment rights to protest government policy.
The documents emerged in ongoing litigation over federal immigration enforcement tactics. Lawyers representing affected groups argue the surveillance chilled legitimate political speech and advocacy, particularly among immigrant communities and their allies.
What Happens Next
The court filing asks federal judges to examine whether the surveillance violated constitutional protections against unreasonable searches and monitoring of political activity. The case could clarify legal limits on federal agents tracking domestic groups based on their political organizing.
Similar surveillance programs targeting political activists have faced legal challenges in other jurisdictions, with courts weighing law enforcement security concerns against First Amendment protections. The Minnesota case adds to ongoing debates about domestic surveillance authority and oversight of federal agencies monitoring American citizens engaged in political advocacy.

- Federal agents monitored progressive activists and unions in Minneapolis during Trump administration immigration enforcement operations
- Two programs tracked groups organizing protests against deportation raids, raising First Amendment concerns about surveillance of political activity
- Court filing asks judges to rule whether the monitoring violated constitutional protections against government tracking of domestic political groups
