The Romney campaign is reacting harshly to Vice President Joe Biden’s accusation that Mitt Romney and Wall Street will put Americans “back in chains.”

“After weeks of slanderous and baseless accusations leveled against Governor Romney, the Obama Campaign has reached a new low,” press secretary Andrea Saul said in a statement. “The comments made by the Vice President of the United States are not acceptable in our political discourse and demonstrate yet again that the Obama Campaign will say and do anything to win this election.
