A Miami federal judge said Tuesday she was “surprised and shocked” when state Attorney General James Uthmeier first told police officers to obey her order not to arrest undocumented immigrants entering Florida but later said he “cannot prevent” them from making arrests under a new state law.

U.S. District Judge Kathleen Williams is considering whether to find Uthmeier in contempt of court.

Williams issued a preliminary injunction late Tuesday prohibiting all state law enforcement officials and police agencies from arresting undocumented immigrants who come into Florida. She also scheduled a critical hearing for late May that could lead to Uthmeier being held in contempt of court for flouting her prior restraining order in the immigration case.
