School district leaders and education associations have become concerned about protecting children in K-12 schools from “raids” targeting illegal immigrant students under President Donald Trump’s leadership, but officials have yet to see a child arrested at school nationwide.

Across the country, school districts in Los Angeles, Chicago, and Denver have reported large swaths of students staying home from school out of fear of being arrested by Immigration and Customs Enforcement officers inside their classrooms ever since the Trump administration opened up schools as locations to make arrests.
