Arizona's governor has asked a judge to dismiss the Justice Department's challenge to the state's new immigration law.

Attorneys for the state have argued the lawsuit is based on speculation and it lacks proof of any actual harm from the measure. The law is set to take effect on Thursday.

Meanwhile, a similar immigration legal battle is playing out in an eastern Nebraska town. Voters in Fremont approved a ban on hiring or renting property to illegal immigrants. The law is being challenged by several groups, including the American Civil Liberties Union

It has been estimated implementing the ordinance would cost the city around $1 million per year in legal fees, employee overtime and improved computer software.

"It just boils down to the fact that the restraining order and injunction is imminent," the council's president Scott Getzschman said. "And as a city of Fremont, we're looking at ways of reducing costs."

The City Council is scheduled to vote Tuesday night on suspending the ban.
