The Trump administration has asked a military base outside of Chicago for support on immigration operations. The move offers a clue of what its expanded law enforcement crackdown might look like in the nation's third-largest city. A base spokesperson says the Department of Homeland Security asked Naval Station Great Lakes for "limited support in the form of facilities, infrastructure, and other logistical needs to support DHS operations." The spokesperson says no decisions have been made on the request, and that the base hasn't received an official request to support a National Guard deployment. Mayor Brandon Johnson and Illinois Gov. JB Pritzker have pushed back against a possible mobilization, saying crime has fallen in Chicago. They plan to sue.

Investigators in Minneapolis say the shooter who killed two Catholic school students and wounded 18 other people inside a church had become obsessed with the thought of killing defenseless children. Police said Thursday that the shooter idolized mass killers and wanted to terrorize innocent children. The police chief in Minneapolis says the shooter, identified as 23-year-old Robin Westman, fired 116 rifle rounds through stained-glass windows Wednesday morning. The children were celebrating Mass during the first week of classes at the Annunciation Catholic School. Acting U.S. Attorney Joe Thompson says videos and writings the shooter left behind show Westman expressed hatred toward almost every group imaginable.

President Donald Trump's threats to deploy National Guard troops to Chicago sent ripples through America's third-largest city as residents defended their home against Trump's escalating rhetoric toward violent crime, including claims Chicago is a "killing field." In a city on edge awaiting news of a potential National Guard deployment, the threat of federal troops stirred a mix of fear, frustration and defiance for residents as they pointed to historic drops in violent crime in the city. Some said it could make things worse with military personnel not being trained in de-escalating violence the way community activists and police are.
