In Michigan, Republican Mitt Romney took a swipe at the president --- reviving the controversy surrounding Obama's birth certificate.<br/> <br />SOUNDBITE: Republican Presidential Candidate Mitt Romney saying:<br/> <br />"I love being home in this place that Anne and I were raised. Where both of us were born. Anne was born in Henry Ford hospital, I was born in Harper hospital. No one has ever asked to see my birth certificate, they know that this is the place we were born and raised."<br/> <br />Obama, the son of an American mother and a Kenyan father, has released multiple copies of his birth certificate showing he was born in Hawaii. This, however, has done little to stop some conservatives speculation about his eligibility.<br/> <br />Romney's comments came just days before the Republican National Convention in Florida.
