Chuck Schumer: Arizona Immigration Law Author Will Testify, But Not Gov. Jan Brewer

WASHINGTON -- Sen. Chuck Schumer is trying to shame Arizona Gov. Jan Brewer into testifying before his subcommittee on immigration.

The Republican governor has already declined an invitation from the New York Democrat to speak to senators about her state's controversial immigration law when she comes to Washington in April. Brewer will be in the nation's capital for a Supreme Court argument on the law, which a lower court has found to be at least partially unconstitutional.

But Schumer has now landed the law's author, former state Sen. Russell Pearce, who lost a recall election last year in part because of anger over the measure. Pearce has agreed to testify before the Senate Judiciary Subcommittee on Immigration, Border Security and Citizenship, which Schumer chairs.

“Other Arizona officials responsible for this law are willing to come and defend it, but not Gov. Brewer," Schumer said in a statement on Tuesday. "The governor is the one who signed this bill into law; she shouldn't leave the defense of it to others.”

The state law would allow police to arrest anyone they suspected of being an undocumented immigrant if they stopped that person for some other reason and found the person was not carrying proper papers. Some critics say the measure amounts to racial profiling.

Lower courts have stayed that part of the law, and the high court will hear the challenge on April 24. Brewer's office has said she will be in town at the time, but deemed Schumer's invitation a "publicity stunt."
