The Supreme Court is letting stand a lower court's ruling barring Florida from enforcing a contentious immigration law that imposes criminal penalties against undocumented migrants who enter the state.

At least seven states, including Texas, Oklahoma and Iowa, have passed similar laws in recent years. All are blocked for now or have not yet taken effect.

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.
