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.

The U.S. Supreme Court maintained on Wednesday a judicial block on a Republican-crafted Florida law that makes it a crime for immigrants in the United States illegally to enter the state. The justices denied a request by state officials to lift an order by Florida-based U.

The law, enacted this year, made it a crime for unauthorized migrants to enter the state. Challengers say immigration is a federal matter.
