Jen Psaki is joined by Stacey Abrams to discuss Kamala Harris' increasingly powerful attacks on Donald Trump about "the enemy within." Next, Jen reflects on Harris' speech in Erie, Pennsylvania where the Vice President played clips of Trump's own words. Jen explains why we should believe Trump when he says what he is going to do in a potential second term. Former Rep. Joe Walsh and political columnist Dana Milbank join the show to discuss the state of the race and the urgency that Harris faces to show voters just how dangerous Trump is. Later, Jen explains how Trump and his allies' lies are causing real harm in communities across America - from Springfield, Ohio to Rutherford County, North Carolina. Jen is also joined by Chris Wallace to discuss his new book "Countdown 1960" focused on the presidential race between JFK and Richard Nixon, and the key lesson it holds for peaceful transfers of power and maintaining democracy.
