Romney On Attack in Pa.

Mitt Romney is seizing on a comment from President Barack Obama as evidence that the Democrat favors a government-centered society.

Obama told supporters in Virginia last week that entrepreneurs didn't build their businesses on their own. He cited government research that helped create the Internet.

Romney said Tuesday that Obama's comment was "startling and revealing."

The likely Republican presidential nominee is intensifying attacks against the president as Democrats and a growing number of Republicans urge Romney to release several years of personal income tax returns.

Romney told a Pittsburgh-area crowd that "he's ashamed" that Obama "hands out money to the businesses of campaign contributors." He also said Obama's suggestion that successful business leaders got government help is "just foolishness."
