Tensions escalated outside the ICE facility in South Portland on Tuesday night, where federal officers deployed pepper balls from the roof, patrolled nearby streets, and arrested at least four individuals.The four people were taken into the facility, though at least one was later released. Authorities did not immediately disclose what charges, if any, the individuals faced, according to KATU-TV.The heightened federal presence on Tuesday followed President Donald Trump’s authorization over the weekend to deploy 200 members of the Oregon National Guard to help protect federal buildings in the city, including the ICE facility. It also comes amid a Democrat-fueled federal government shutdown after they refused to back a clean continuing resolution ahead of a midnight deadline.State, county, and local officials in Oregon pushed back on the president’s characterization and the deployment of federal resources, arguing that they are capable of managing the protests without additional federal intervention.
