It's President Obama's policy not to secure America's southern border. Yesterday, his administration filed suit against Arizona for its new law to try to enforce immigration statutes already on the books. This comes after the administration brought legal action against the Grand Canyon State for a 2007 law that strips business licenses away from companies that violate immigration laws. It's clear the White House is working to make states defenseless against an illegal invasion.
