Picking a running mate: Inside the 16 days between Kamala Harris' launch and her choice of Tim Walz

Kamala Harris’ whirlwind process to select Minnesota Gov. Tim Walz as her running mate can be summed up in a word: weird. Vetting, interviews and the final decision are usually spread over months, not days. But the vice president didn't have months. She was thrust into the role of party standard-bearer on July 21 when President Joe Biden stepped aside as Democrats' presumptive nominee. What followed was a 16-day compressed process. There was the fast-track private vetting work. And a conspicuous public audition by multiple contenders. In the end, she chose a governor who did not start out as a perceived front-runner. Aides said Walz won out ultimately as the best potential governing partner in a Harris administration.
