Five Democratic lawmakers are suing and asking the Florida Supreme Court for access into the “Alligator Alcatraz” immigration detention facility after they said they were blocked from entering to inspect the conditions.

Florida lawmakers argued state law grants elected officials access to inspect state-operated facilities without approval, but the Florida Division of Emergency Management denied their request.

Florida lawmakers worried about “humanitarian concerns” were denied entry into the new detention center dubbed as “Alligator Alcatraz” Thursday, just hours after the arrival of its first group of detainees.
