Sarah Parise and her 2-year-old daughter Leia were exposed to tear gas deployed by Border Patrol agents during immigration enforcement operations in the Old Irving Park neighborhood on October 25. While walking near a grassy field, Parise and her daughter were struck by chemical agents without warning; Leia screamed in pain as Parise ran home and rinsed them with water and milk. A federal judge questioned the use of tear gas in the operation, which resulted in one arrest.
