The acting director of Immigration and Customs Enforcement on Tuesday defended the agency’s decision last week to arrest an illegal immigrant who was on the way to his prom.

ICE Acting Director Thomas D. Homan was asked at a House Appropriations Committee hearing about Diego Puma Macancela, a 19-year-old who was detained last week. Rep. Nita Lowey, D-N.Y., asked if it’s an ICE policy to target students on the way to school or church.
