Romney: 'No one's ever asked to see my birth certificate'

Presumptive Republican presidential nominee Mitt Romney came the closest yet on Friday to personally embracing the so-called birther movement's theory that President Barack Obama is not a U.S. citizen.

"I love being home in this place where Ann and I were raised, where both of us were born," the former Massachusetts governor told a group of supporters in Michigan. "Ann was born at Henry Ford Hospital, I was born at Harper Hospital."

"No one's ever asked to see my birth certificate," he added. "They know that this the place that we were born and raised."

Late last year, Romney's son, Matt, also promoted the theory that the president was not born in the United States.

Stumping for his dad in Concord, New Hampshire, Matt Romney told a group of senior citizens that the multimillionaire candidate might not release his tax returns until Obama releases his birth certificate, a document that was made public long ago.

“He has not said that he will not do it,” the younger Romney said of the tax returns, sounding like the son of a politician. “He has also not said that he will. I think it’s just a matter of time until that issue comes up. So, I don’t know the answer to that. I’m not sure he knows the answer to that.”

“I heard someone suggest the other day that as soon as President Obama releases his grades and birth certificate and sort of a long list of things then maybe he’d do it,” he joked.

Matt Romney later told KITV that he was "satisfied" the president was born in Hawaii.
