The race for the White House kicking into high gear as we're counting down to tomorrow's presidential debate. This will be the first and maybe the only debate between Vice President Kamala Harris and former president Donald Trump in Philadelphia NB C's Hallie Jackson has the latest. Their first face off just one day away with the stage and the candidates set to go. Vice President Harris with a thumbs up in Pittsburgh where she's been prepping two sources familiar with the sessions say she's been practicing with extended mock sessions on specific topics and getting ready in case Mr Trump were to lash out. Look, it's time to turn the page on the divisiveness. Harris stopping at a spice shop in Pittsburgh for his part, the former presidents holding policy sessions to prepare for the debate. One front, Mr Trump sees as a potential policy weakness for Harris, the US withdrawal from Afghanistan. And this morning House Republicans are releasing a scathing new report saying Biden administration officials watered down security warnings ahead of the chaotic withdrawal. A withdrawal initiated by former President Trump Democrats have dismissed the report in advance as partisan and the White House says it's based on cherry picked facts and inaccurate characterizations ahead of tomorrow's debate. Some allies of the former president's suggest he should focus on policy and avoid personal attacks. I think that when he stays on the issue's policies. Absolutely, those are, those are the winning issues for President Trump on the trail in battleground Wisconsin. This weekend, we're run by stupid people and we found that out at the debate with Joe, how did that work out? And we're going to find that out again on Tuesday night and in a social media post online suggesting he may imprison his political opponents if he wins repeating his election fraud lie and writing anyone believed to have cheated will be prosecuted to the fullest extent of the law which will include long term prison sentences. The latest signal, he may not accept the results if he loses. Mr Trump also blasting former vice president Dick Cheney and his daughter Liz, the former congresswoman and Trump critic for endorsing Kamala Harris. Donald Trump presents a challenge and a threat uh fundamentally to the Republic.
