DES MOINES, Iowa -- One of Mitt Romney's sons has an answer for those who say his father should release his tax returns. He jokes that President Barack Obama should go first and release his birth certificate and other records.
Matt Romney's wisecrack came before an audience in New Hampshire on Friday. In response on Twitter, the Obama campaign tweeted, in part, "Guess he doesn't have one of our mugs?"
The Obama campaign sells mugs with a picture of Obama's birth certificate.
Matt Romney was appearing with three of his brothers when he said in regard to the tax return question: "I heard that someone suggested that as soon as President Obama releases his grades, and birth certificate, and a sort of a long list of things, then maybe he will."
Brother Tagg Romney jumped in and said, "That was not my dad who said that."
Matt Romney later tweeted regret that he'd repeated what he called "a dumb joke."
Mitt Romney has refused to release his tax returns but says he'd reconsider if he were the GOP nominee for president. Obama released his tax returns during the 2008 Democratic primary and in each year of his presidency.
The Romney campaign took a different kind of swipe at Obama, calling via a new website for $18 donations as a response to Obama playing golf while on vacation in Hawaii – a dollar a hole.
