Yes, he went there.

Mitt Romney made a birth certificate joke today, prompting President Obama's campaign to accuse him of lining up with the so-called "birther" movement.

During an appearance in his native Michigan today, Romney said: "No one has ever asked to see my birth certificate -- they know that this was the place we were born and raised."

Some of President Obama's most intense critics continue to question whether he was born in the United States, despite his 2011 production of a birth certificate from Honolulu.

Obama's campaign quickly condemned the comments.

"Throughout this campaign, Gov. Romney has embraced the most strident voices in his party instead of standing up to them," said Obama campaign spokesman Ben LaBolt.

Referring to so-called "birthers" who are expected to be at next week's Republican convention, LaBolt said:

"It's one thing to give the stage in Tampa to Donald Trump, Sheriff (Joe) Arpaio, and Kris Kobach. But Gov. Romney's decision to directly enlist himself in the birther movement should give pause to any rational voter across America."

Another Obama aide, Jen Psaki, told MSNBC that "this is a pattern," and Romney has repeatedly questioned whether the president "understands" the United States.

Romney later told CBS News he was only joking.

"There's no question about where he (Obama) was born," Romney said. "He was born in the U.S."
