Congressional Democrats, flush with new majorities after this week's midterm elections, are preparing to launch wide-ranging investigations into the fatal shootings of two U.S. citizens by federal immigration agents during last winter's enforcement surge in Minneapolis. The deaths of Renee Good, a mother of three, and Alex Pretti, a VA nurse, both killed by ICE and Border Patrol personnel in January, became a flashpoint in the national debate over President Trump's deportation crackdown. With subpoena power now in hand, Democrats say they will compel testimony from the architects of that crackdown and demand internal documents the administration has so far refused to release. Maryland Rep. Jamie Raskin, expected to chair the House Judiciary Committee, said Congress will use "every tool" available to investigate ICE and that the agency must "start answering to the American people." California Rep. Robert Garcia, in line to lead the Oversight Committee, put it more bluntly: "Lawyer Up." Mississippi Rep. Bennie Thompson, the incoming Homeland Security chairman, fired off a letter Wednesday to Homeland Security Secretary Markwayne Mullin demanding the department "comply with all document preservation requirements." Illinois Rep. Delia Ramirez said on social media that Mullin, White House Chief of Staff Stephen Miller, Border Czar Tom Homan, former Homeland Security Secretary Kristi Noem and former Border Patrol Commander Gregory Bovino should clear their schedules. The Department of Homeland Security is not rolling over. General Counsel James Percival dismissed the effort as "political shenanigans" and said the agency is ready to "deal with this nonsense." A White House spokesperson warned that Democrats pursuing "sham investigations and radical left policies" are working against the American people, adding that the administration still controls the federal government and its powers. But critics of the administration say the probes are long overdue. Federal law enforcement has offered little indication it is making progress on investigating the Good and Pretti deaths, or the killings of at least seven other people by federal immigration agents since Trump returned to office. DHS did not respond to questions about the status of those investigations. Naureen Shah of the ACLU said congressional hearings could finally force answers to basic questions: What orders were given to officers in the field? What kind of training did they receive? And who decided to portray Good and Pretti as threats, including labeling Pretti a "would-be assassin" and a domestic terrorist when video evidence suggested otherwise? "It's like we can turn the faucet on and actually find out so much more," Shah said. There are limits. Rachel Moran, a law professor at the University of St. Thomas, noted that clawing back ICE funding would require a veto-proof majority Democrats do not have, and the president has shown little appetite for holding federal agents accountable. Still, she said, a deeper congressional probe could surface evidence that states could use in their own criminal cases. Minnesota officials have been battling the federal government for access to evidence in the Good and Pretti shootings. Brent Ganger, Good's brother, said learning the full truth about his sister's death will be painful but necessary. "I don't want history to keep repeating itself," he said. In Minneapolis, mourners have spent the week placing "I Voted" stickers at the memorials where Good and Pretti were killed, a quiet signal that they expect the new Congress to act. "You work for us," said Nicki Adams, Pretti's former girlfriend and close friend for nearly 17 years. "We want to be seen and heard and taken care of and have our neighbors taken care of."
