Thousands of Portlanders took part in peaceful May Day demonstrations on May 2, 2026, marking International Workers' Day and linking labor rights with immigrant rights. By evening, hundreds marched to the ICE facility in South Portland, where five people were arrested after police said protesters threw rocks and water bottles at officers; one officer was hospitalized after being struck by a large rock, and another was treated at the scene. Seven additional arrests were made during a hotel sit-in on Southwest 2nd Avenue. The march came two days after a 9th Circuit Court of Appeals panel stayed earlier federal court orders limiting agents' use of crowd control munitions, and police said the Portland Police Bureau has made 94 arrests tied to ICE protest activity since June 2025.
