Vice President Kamala Harris and her running mate, Minnesota Gov. Tim Walz, will sit down for their first major television interview of their presidential campaign, as the duo travels in southeast Georgia on a bus tour. Thursday's interview with CNN’s Dana Bash will give Harris a chance to quell criticism that she is unprepared for uncontrolled environments, define her campaign and test her political mettle ahead of an upcoming debate with former President Donald Trump set for Sept. 10. But the interview also carries risks as her team tries to build on momentum from the ticket shakeup following Joe Biden’s exit and the Democratic National Convention.
