The Supreme Court has agreed to rule on
Arizona's controversial law aimed at cracking down on illegal immigration.
The justices said Monday they will review a federal appeals court ruling that blocked several tough provisions in the Arizona law.
One of those requires that police, while enforcing other laws, question a person's immigration status if officers suspect he is in the country illegally.
The Obama administration challenged the Arizona law by arguing that regulating immigration is the job of the federal government, not states.
Proponents of the law say the federal government has failed in its responsibility to halt illegal immigration.
Similar laws in Alabama, South Carolina and Utah also are facing administration lawsuits.
The court now has three politically charged cases on its election-year calendar. The other two are President Barack Obama's health care overhaul and new electoral maps for Texas' legislature
and congressional delegation.
