US v. Sant — Clearview AI in ICE protest surveillance (2026)

Homeland Security Investigations and the federal agencies conducting Operations Puppet Master, Whipple Shield and Metro Surge; Clearview AI as the search provider
Enforced by
United States District Court (District of Minnesota; not expressly named in the located source)

Court records filed as exhibits to a defense discovery motion in the prosecution of Isaac Sant — one of fifteen defendants accused of conspiring to impede federal immigration officers during OPERATION METRO SURGE in Minnesota — disclose how Homeland Security Investigations combined facial recognition with undercover human surveillance of activists. At least TWO CLEARVIEW AI SEARCH REPORTS were produced in the case. One of them RETURNED PHOTOGRAPHS OF ANOTHER MAN as possible matches, AND INCLUDED FACEBOOK IMAGES OF THAT MAN'S WIFE AND CHILD. That single detail is the most important thing in this entry: a facial recognition search run on one person swept in a different, uninvolved person and then his family, including a child, none of whom were suspects in anything. The facial recognition sat inside a much larger operation. HSI personnel conducted UNDERCOVER INFILTRATION OF ACTIVIST GROUPS, monitored encrypted communications, recorded license plates, and compiled intelligence files combining facial recognition results with vehicle records and social media data. Undercover agents attended meetings at CHURCHES, LIBRARIES, SCHOOLS AND UNION FACILITIES, secretly recording conversations and accessing encrypted activist communications. Three named operations appear in the records: Operation Puppet Master, opened January 28; Project Whipple Shield, in February; and Operation Metro Surge. Defense attorneys are seeking comprehensive records to establish the scope of the surveillance and whether FIRST AMENDMENT protections were violated. Nothing here has been ruled on; these are disclosures in a pending criminal case.

Who is protected: Activists and protesters in Minnesota subject to the surveillance; uninvolved third parties swept in by facial recognition searches, including the man, wife and child identified in the records; congregants, library users, students and union members present at infiltrated meetings

Legal detail

United States v. ISAAC SANT (and 14 co-defendants), Minnesota — court records filed as EXHIBITS TO A DEFENSE DISCOVERY MOTION in a prosecution charging conspiracy to impede federal immigration officers during OPERATION METRO SURGE. DISCLOSED SURVEILLANCE ARCHITECTURE: HOMELAND SECURITY INVESTIGATIONS (HSI) combined (a) CLEARVIEW AI FACIAL RECOGNITION \u2014 at least TWO CLEARVIEW AI SEARCH REPORTS were produced; (b) UNDERCOVER INFILTRATION of activist groups; (c) MONITORING OF ENCRYPTED COMMUNICATIONS; (d) LICENSE PLATE RECORDING; and (e) INTELLIGENCE FILES COMBINING facial recognition results with vehicle records and social media data. THE COLLATERAL-SWEEP DETAIL IS THE CORE FINDING: one Clearview search 'returned photographs of ANOTHER MAN as possible matches and included FACEBOOK IMAGES OF THE MAN'S WIFE AND CHILD'. A single facial recognition query therefore produced a dossier on an uninvolved third party and his family including a minor, none of them suspects. This is the concrete mechanism behind the objection that face search against scraped social media corpora cannot be contained to its target \u2014 the system returns a person, and the person's relationships come with them. UNDERCOVER VENUES, recorded because of their constitutional sensitivity: agents attended meetings at CHURCHES, LIBRARIES, SCHOOLS AND UNION FACILITIES, secretly recording conversations and accessing encrypted activist communications. Surveillance of religious worship, public libraries, educational institutions and labour organising implicates association and religious exercise interests distinct from ordinary investigative privacy. NAMED OPERATIONS: OPERATION PUPPET MASTER (opened January 28), PROJECT WHIPPLE SHIELD (February), OPERATION METRO SURGE. DEFENSE POSTURE: attorneys seek comprehensive records to determine the scope of surveillance and WHETHER FIRST AMENDMENT PROTECTIONS WERE VIOLATED. STATUS: a discovery dispute inside a pending criminal prosecution. NOTHING HERE HAS BEEN ADJUDICATED; the facts are as stated in records filed by the defense, and strength is `unknown` accordingly. This dataset indexes other Clearview matters (ACLU v. Clearview AI, In re Clearview AI Class Settlement) but had NO record of federal protest-surveillance use.
