Congressional Democrats made an impassioned plea for Arizona's new immigration law to be overturned, citing constitutional concerns and other implications for the country. Slated to go into effect 90 days after the close of Arizona's legislative session, the law would require immigrants to carry alien registration documents at all times and require police to question people if there's reason to suspect they're in the United States illegally. Critics say they are concerned it will foster racial profiling and argue the new Arizona law is in conflict with federal law. Supporters say it's just another tool that law enforcement has in cracking down on illegal immigration.
