Justices said the "show me your papers" provision could still be subject to additional legal challenges.

President Obama said he is "pleased" with the decision but concerned about the remaining provision.

"What this decision makes unmistakably clear is that Congress must act on comprehensive immigration reform. A patchwork of state laws is not a solution to our broken immigration system – it’s part of the problem. At the same time, I remain concerned about the practical impact of the remaining provision of the Arizona law that requires local law enforcement officials to check the immigration status of anyone they even suspect to be here illegally. I agree with the Court that individuals cannot be detained solely to verify their immigration status. No American should ever live under a cloud of suspicion just because of what they look like. Going forward, we must ensure that Arizona law enforcement officials do not enforce this law in a manner that undermines the civil rights of Americans, as the Court’s decision recognizes."

Mitt Romney released a statement shortly after the decision. Romney said the decision shows the need for bipartisan immigration reform.

“Today’s decision underscores the need for a President who will lead on this critical issue and work in a bipartisan fashion to pursue a national immigration strategy. President Obama has failed to provide any leadership on immigration. This represents yet another broken promise by this President. I believe that each state has the duty–and the right–to secure our borders and preserve the rule of law, particularly when the federal government has failed to meet its responsibilities. As Candidate Obama, he promised to present an immigration plan during his first year in office. But 4 years later, we are still waiting.”
