The small town of Dilley, where the Congressman had picked up the father and his famous son, has become familiar terrain for Castro, even though it’s about an hour’s drive southwest from his district in San Antonio. The Biden Administration stopped holding immigrant families there in 2021. The federal government reopened it last year to detain women and families caught up in President Donald Trump’s immigration crackdown. Castro says he’s spoken with hundreds of children and parents in the facility and that the conditions there should be a national scandal.
