Cali Overs, a 17-year-old student body vice president at Dysart High School in Surprise, Arizona, is leading student opposition to a planned ICE detention facility being built about a mile from her school. The Department of Homeland Security purchased a 418,400-square-foot warehouse in January 2026 to convert into an immigration detention center with up to 542 beds. Overs has spoken at city council meetings, met with federal lawmakers and state officials, and advocated for a three-mile buffer zone between ICE facilities and schools, given that Hispanic students comprise over 60% of her school's population.
