Kamala Harris acknowledges Biden had a ‘slow start' in debate, tries to calm Democratic fears

PHILADELPHIA, PENNSYLVANIA - MAY 29: U.S. President Joe Biden and U.S. Vice President Kamala Harris stand on stage at the conclusion of a campaign rally at Girard College on May 29, 2024 in Philadelphia, Pennsylvania. Biden and Harris are using today's rally to launch a nationwide campaign to court black voters, a group that has traditionally come out in favor of Biden, but their support is projected lower than it was in 2020.
