Michigan state Sen. Tom Casperson, a Republican, said Tuesday he wasn't sure whether President Barack Obama was born in the United States.

"I don’t know because it seems like that issue was dropped immediately as far as the major media went," he said on Michael Patrick Shiels' radio show. "My gut tells me if it had been a different president, like say George W. Bush, they’d have been digging into like there was no tomorrow and trying to get to the bottom of, which they never really tried to get to the bottom of, so it became a conspiracy theory and no big deal."

"I think it is strange, again, that it is not being looked at by certain groups that normally would," Casperson added. "I think what the media did to George W. Bush was OK. They kept his feet to the fire, but I think they equally should be doing the same thing to this president."

His comments were captured by the group Progress Michigan.

“Questioning the President’s birthplace is like believing in Bigfoot or the Loch Ness Monster,” said Zack Pohl, Executive Director of Progress Michigan. “Sen. Casperson should immediately apologize and acknowledge that Obama was born in the United States. We need elected leaders who are focused on creating jobs and improving education – not wild Tea Party conspiracy theories.”

My so-called "birthers" believe Obama was born in Kenya and that his birth certificate was forged to make him eligible for the presidency. Judges have repeated dismissed “birther” lawsuits against Obama’s right to be president as frivolous. The President has released his long-form birth certificate and state officials have confirmed Obama was born in Hawaii.
