Biden compares Republicans to 'squealing pigs'

Vice president sounds off on regulating Wall Street

Vice President Biden is trading his claim that Republicans want to put people "back in chains" for some new imagery -- this time likening GOP lawmakers to "squealing pigs."

The vice president, during a speech in Minneapolis, attacked Republicans on Tuesday over their objections to recent financial regulations.

"Over the objections where they sound like squealing pigs, over the objections of (Mitt) Romney and all his allies, we passed some of the toughest Wall Street regulations in history," Biden said, claiming Democrats ensured Wall Street is no longer a "casino."

The language follows a trend of amplifying rhetoric on the campaign trail in the run-up to the Republican and Democratic national conventions.

It also comes after Biden last week told a Virginia crowd that Republicans want to unshackle Wall Street and "put y'all back in chains." The comments to the mixed-race Virginia audience prompted accusations that the vice presidential was employing racial overtones, but the campaign denied it and defended its criticism of those who resisted financial regulation.

Biden has since moved away from the "chains" language but continues to hammer the regulatory message.

The vice president unloaded on Romney and running mate Paul Ryan throughout his speech Tuesday, on everything from China policy to Medicare.

Biden is assuming an aggressive role for the Obama campaign as the GOP convention approaches. The campaign confirmed Tuesday that he plans to be in Tampa, the convention city, on opening day next Monday.
