Florida passed a law making it a crime for people in the U.S. illegally to enter the state. A federal judge said it's likely unconstitutional.

Florida cannot enforce a new law that would bar illegal immigrants from entering the Sunshine State, the Supreme Court ruled on Wednesday. “The application for stay presented to Justice Thomas and by him referred to the Court is denied,” read the order rejecting Florida’s emergency appeal to the high court.

The U.S. Supreme Court blocks Florida’s anti-immigrant law, affirming federal control over immigration enforcement and halting state-level criminalization.
