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 Supreme Court has refused to allow Florida to enforce an immigration law making it a crime for people who are living in the U.S. illegally to enter the state.

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