An undercover Homeland Security Investigations agent attended an April event in Ann Arbor focused on resistance to U.S. Immigration and Customs Enforcement, according to federal investigative records. 

It was part of a broader DHS surveillance effort connected to Operation Metro Surge in Minnesota, the major immigration action in and around Minneapolis in January 2026 during which federal immigration agents shot and killed Alex Pretti and Renee Good.
