Several hundred protesters gathered at Portland's ICE facility on May Day, with some marching onto the facility's driveway and rattling its gate before Portland police and Oregon State Police moved in to clear the area and make arrests. Officers said protesters threw rocks and water bottles, injuring an officer, while ICE agents remained inside the building throughout the confrontation. Police had made arrests earlier in the day, including nine people during a hotel sit-in demonstration, with additional arrests made near the ICE facility as the evening protest intensified. A police spokesperson said officers' intervention was prompted when demonstration activity "turned criminal."
