John is joined by Nicolle Wallace—host of Deadline: White House on MSNBC, former aide to George W. Bush and John McCain, and author of three bestselling novels (Eighteen Acres, It’s Classified, and Madam President) about life inside the White House—to discuss Kamala Harris’s selection of Tim Walz as her running mate and its potential impact on the election. The two close friends talk about the secrecy and mystery surrounding every veepstakes, the factors driving Harris to pick the relatively unknown Walz over popular Pennsylvania Governor Josh Shapiro, and why Wallace says that the aftermath of Joe Biden’s disastrous debate performance and his eventual departure from the presidential race was the hardest story she’s ever had to cover as an MSNBC anchor.
