CHICAGO, - Potential Republican presidential contender Mitt Romney finished a day of fundraising in Chicago by sending leftover pizza to President Obama's campaigners. Romney said he enjoyed the deep-dish pizza at Gino's East and sent some to Obama's Chicago re-election headquarters, ABC News reported Friday. "Great deep dish at @ginoseast. Sending the extra slices to @barackobama and his Chicago HQ team," Romney wrote on his Twitter feed. The message was accompanied by a picture of a delivery boy heading out of the restaurant.
