The law signed by Gov. Ron DeSantis makes it a state crime to enter Florida after coming into the United States illegally and to re-enter the state following deportation.

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

Supreme Court blocked Florida on Wednesday from enforcing a law that would make it a crime for undocumented migrants to enter the southern state. A federal district judge had put the law on hold in April on the grounds it constituted state interference with federal immigration policy.
