Nearly two dozen people were arrested on Friday outside a federal immigration facility near Chicago, authorities said, the latest sign of tensions over the Trump administration's aggressive enforcement push. Since Trump intensified ICE operations in Chicago in September, demonstrators have regularly clashed with authorities, who have fired tear gas, less-lethal rounds, flash-bang grenades and pepper balls. The U.S. Department of Homeland Security, ICE's parent agency, did not immediately respond to a request for comment regarding Friday's protests.
