As the Harris and Trump campaigns negotiate whether candidates will be muted during the upcoming presidential debate, Jen Psaki reflects on how the more people hear from Donald Trump, the less they like. Don Lemon joins Jen to discuss the state of the presidential race and his new book "I Once Was Lost: My Search for God in America". Next, Ian Sams, senior advisor for the Harris-Walz campaign, joins the show to discuss topics including Trump's push for muted mics at the debate, the influx of Republicans endorsing Kamala Harris, and Trump's continued legal troubles. Later, Senator Elizabeth Warren joins Jen to discuss Kamala Harris' ambitious affordable housing plan and the Trump-Vance campaign's efforts to conceal their plans to ban abortion, among other topics. Finally, Jen breaks down the GOP's bizarre and baseless conspiracy theory about Tim Walz's dog.
