Justice Dept. Files Suit Against AZ

The stage is set for a constitutional showdown: The Department of Justice filed a lawsuit against the state of Arizona Tuesday, challenging its controversial new immigration law. The lawsuit says the Arizona law, which would require police officers to check the immigration status during the enforcement of other laws, usurps federal authority and seeks an injunction against its implementation. (It is set to kick in July 29.) The case was filed in U.S. District Court in Phoenix.
