With a Saturday deadline looming for the controversial Arizona immigration bill, President Obama has come out against it. Speaking at a naturalization ceremony for military members on Thursday, Obama said the bill -- which would allow police to check people's immigration status if they have just a suspicion that they might be illegal -- "threatens to undermine basic notions of fairness that we cherish as Americans."
Watch a clip:
Arizona Gov. Jan Brewer has to take action on the bill by Saturday. She can sign it, veto it, or allow it to become law without her signature. Brewer said she is studying claims that the bill could lead to racial profiling.
"I've been meeting with lawyers, and I’ve been looking at it very diligently," she said.
Arizona is Ground Zero for illegal immigration. Its border with Mexico is the nation's busiest border crossing, and the state has nearly half a million illegal immigrants.
