On the campaign trail, Vice President Joe Biden is under fire for what Republicans call an attempt to link Mitt Romney to the policies of slavery. Speaking in Virginia, Biden said Romney wants to put Americans “back in chains” through his opposition to financial regulation.

Joe Biden “Every Republican’s voted for it. Look at what they value and look at their budget and what they’re proposing. Romney wants to let the — he said in the first hundred days he’s going to let the big banks once again write their own rules, 'unchain Wall Street.' They’re going to put y’all back in chains.”

Biden has stood by his remarks, saying he intended no comparisons to slavery.
