GOP vice presidential candidate Paul Ryan took a shot at Vice President Joe Biden Thursday over his latest gaffe.
Biden on Tuesday mistakenly told a crowd in Danville, Va., that they could help President Obama win North Carolina in November.
"We can win North Carolina again," Biden said.
Biden is enduring a difficult week on the campaign trail. He also made headlines on Tuesday when he told a crowd in Virginia that the GOP ticket would "put y'all back in chains" by undoing financial reforms for Wall Street. The Republican ticket hammered Biden over the remarks, but Biden said GOP policies were more outrageous than anything he said.
