Former Rep. Tim Walberg (R-Mich.), who is running to oust Rep. Mark Schauer (D) this fall, was asked on a local radio show Thursday whether he believed President Obama was born in the United States and whether the president is Muslim.

"I don't know, I really don't know," Walberg responded. "We don't have enough information about this president. He was never given a job interview that was complete."

Walberg continued: "But that's not the issue now. He is president. Right now we need to make sure he doesn't remain as president, whether he's American, a Muslim, a Christian, you name it."

The question came from a listener who told Walberg he hasn't seen enough evidence to suggest that the president is, in fact, an American citizen.

The so-called "birther" claims harken back to the 2008 presidential race, when a series of chain e-mails circulated with false claims that Obama was not born in the United States and is Muslim. The president was born in Hawaii and is Christian.

Here's a link to a shortened version of Walberg's radio interview. You can listen to the complete audio of the interview here.

Walberg is running to reclaim his old seat after Schauer ousted him in 2008.

The latest polling in the rematch shows a tight race. New numbers out Friday from the Rossman Group give Walberg a slight lead over the incumbent, 42 percent to 38. Schauer has countered with internal numbers that his camp says have him up four points.
