A lighter moment on Mitt Romney's campaign jet Saturday -- as the Republican presidential nominee enjoyed a little traditional "orange bowling".
Members of the media pool traveling with the candidate wrote a question for Romney on an orange, and rolled it down the plane's aisle.
Romney wrote down his answer -- and rolled the orange right back.
A Los Angeles Times reporter in the media pool says the question was about preparations for the upcoming debate with President Obama.
Romney replied to confirm that Senator Rob Portman of Ohio will play the role of the president in practice debates.
