A judge ruled Wednesday that the Trump administration must facilitate the return of a 20-year-old migrant, who was deported last month, because his removal violated a class action lawsuit settled last year.

A 32-year-old Venezuelan man reportedly took a wrong turn onto the Ambassador Bridge, crossing into Canada, while delivering food back in January, and has since been detained and deported to El Salvador.

It is the latest immigration twist in a growing legal — and political — showdown between two branches of government.
