U.S. Immigration and Customs Enforcement (ICE) conducted mass raids on workplaces in the first week of school in Mississippi. According to reports, the operation was conducted without much advance notice, even to the White House. Six hundred agents took part in raids of chicken processing plants that netted nearly 700 detainees and left some children stranded after school or day care because their parents were taken into custody. About half of those detained were released the next day, as they were determined not to be a public threat, and some were taken back to their workplaces with a summons to appear later in immigration court. The action drew criticism because of the timing—just days after a mass shooting in El Paso, Texas, targeting Hispanic immigrants.
