Okay, something to like on a 102-degree day:

The Obama administration on Tuesday sued Arizona over the state’s strict new immigration law, attempting to wrestle back control over the issue but infuriating Republicans who said the border required more security.

The administration argued the Arizona law, which requires state and local police to investigate the immigration status of anyone they reasonably suspect of being an illegal immigrant, is unconstitutional and would sap law enforcement resources.

   That said, the reasoning that it would "sap law enforcement resources" is less relevant than it doesn’t address the root cause of immigration–the impoverishing of millions of people because of bad economic policy that this country pursues.
