On this week's episode of “The Saturday Show” with Charles Blow in for Jonathan Capehart: Digging in for the Debate. Vice President Kamala Harris says she's ready for her faceoff with Donald Trump while Trump turns up the criticism on the campaign trail. We'll take a closer look at the high stakes of their first and maybe only presidential debate. And surprise support. Former Republican Vice President Dick Cheney and his daughter Liz say they are voting for Kamala Harris. I'll ask my panel why the most prominent political families are lining up against Donald Trump--while one major Republican leader is sitting this one out. Plus a new alliance of advocacy groups is mobilizing Black voters in several swing states. Kristin Powell, is part of that alliance and will discuss their mission. Finally justice denied. Newly-revealed details about the torture and murder of Emmett Till 69 years ago--and the journalist who withheld information about the men who killed the 14-year-old. All that and more on “The Saturday Show” with guest host Charles Blow.
