In a new effort to settle nagging questions about his finances, Republican Presidential pick Mitt Romney today told reporters that his dog ate his tax returns and also served as C.E.O. of Bain Capital from 1999 to 2002.

Mr. Romney’s narrative about the Irish setter Seamus Romney, shared with reporters during a campaign stop in New Hampshire, was perhaps the most emotional invocation of a pet by a politician since Richard M. Nixon’s famed Checkers speech of 1952.

“Seamus was more than a dog,” Mr. Romney said, his voice beginning to quaver. “As C.E.O. of Bain, he was a job creator.”
