Arizona’s secretary of state said Friday he had asked officials in Hawaii to verify that Barack Obama was born in their state in order for the president’s name to appear on the November ballot in Arizona.

Ken Bennett, who is Republican presidential candidate Mitt Romney’s campaign co-chairman in Arizona, said he made the request on behalf of a constituent.

Earlier this year, hardline Arizona sheriff Joe Arpaio announced that an investigation by his office had found that Obama’s birth certificate was a forgery.
