The Obama administration has signaled a willingness to drop its legal fight against a section of Arizona's 2010 immigration law that critics consider racial profiling.

According to court records, a deal between the U.S. Justice Department and Republican Gov. Jan Brewer would end the federal challenge seeking to block a requirement that police question the immigration status of people suspected of being in the country illegally.

In exchange, Arizona would permanently do away with a provision requiring immigrants to carry registration papers, a section courts have blocked on a preliminary basis.

Attorneys on both sides have cautioned in court papers that they haven't yet come up with a proposed court order that would carry out the deal.
