A coalition of civil rights groups has asked a federal judge to block Alabama's new immigration law from taking effect September 1.
The motion, filed by the American Civil Liberties Union, Southern Poverty Law Union and other groups, calls the law blatantly unconstitutional.
On the other side, state Attorney General Luther Strange has asked a federal court to require the plaintiffs to clarify that motion, saying much of it is inappropriately vague and immaterial.
Strange says he hopes the court acts upon his motion before ruling on the request to halt the law.
Governor Robert Bentley, meanwhile, says he supports a strong immigration law.
"I asked for the toughest immigration law that we could have. The legislature passed it and I signed it. We're gonna enforce it. If the federal government would do their job, like they should be doing, states would not have to pass any of these bills. So I'm calling on the federal government to do their job instead of the states having to do their job for them."
Federal courts have blocked all or parts of similar laws passed in four other states.
Alabama's law allows police to detain people they suspect of being in the country illegal during traffic stops, requires schools to report the immigration status of students and makes it illegal to knowingly transport or provide shelter for an illegal immigrant.
