The Bishop Henry Whipple Building in Fort Snelling, Minnesota, which currently serves as a major immigration enforcement processing center, is located on Bdóte, a Dakota creation site that in 1862 became a concentration camp imprisoning thousands of Dakota and Ho-Chunk people during the Dakota Indian Wars. Local residents first raised concerns about the building's use for immigration detainment in 2019. In early 2026, at least three Indigenous people—Jose Ramirez (Red Lake descendant), a Dakota woman, and reportedly four Lakota men—were detained at the building, with Ramirez held for six hours following a confrontation with immigration officials.
