A federal judge on Wednesday temporarily blocked the enforcement of a Florida law that makes it a felony to transport undocumented immigrants into the state, putting in question the fate of a key part of Gov. Ron DeSantis’ immigration agenda.

The state law, which went into effect last July to prevent undocumented immigrants from coming into Florida, has already resulted in arrests and human smuggling charges. In one case, a Mexican national has been detained in a county jail for nearly a year on human smuggling charges after he was arrested for driving six other Mexicans in a van from Georgia into Florida.
