The union-organized protest began several blocks from the Portland ICE building and included a march through the city’s South Waterfront neighborhood. During the march, sometime after 4 p.m., some protesters crowded the immigration building’s driveway, blocking a security gate that leads into the facility.

Federal officers stationed at the ICE building deployed tear gas that drifted through the air, traveling several blocks and into the larger crowd of demonstrators made up of families, including children and elderly people. Many held signs that read “Immigrants are not Criminals Our President Is!!” and “ICE Out of Our Communities,” but were forced to scatter after they were hit by the thick chemical mist.
