Dan Mitchinson: US correspondent ahead of Joe Biden's first extended interview following shaky debate performance

President Joe Biden has lined up his first full interview for ABC News following the fallout of last week's debate. Biden will speak to veteran broadcaster and former Clinton aide George Stephanopoulos on Friday, with the 'extended' version airing on Sunday. US correspondent Dan Mitchinson says this interview won't alleviate the fears from prospective Democrat voters. "You can't unsee what we saw during that debate, that's the problem. They're going to continue to show that over and over and over again, the Republicans are going to use that in every commercial, every possible opportunity."  LISTEN ABOVESee omnystudio.com/listener for privacy information.
