NEW! Federal judge has blocked key provisions of Arizona law

A U.S. District Court ruling has granted the Justice Department an initial win against the state’s immigration law. POLITICO's news alert:

A federal judge has blocked key provisions of a controversial Arizona law aimed at illegal immigrants. The judge blocked a requirement that police have to check the immigration status of detainees they reasonably suspect of being in the country illegally, and stopped part of the law that makes it a crime for immigrants to be in the state illegally.
