 Biden fielded questions for nearly an hour. He stumbled a few times, like when he said Vice President Trump when he meant to say Vice President Harris. He also acknowledged that in his public appearances, he needs to, quote, allay fears. And he covered foreign policy issues from Ukraine to Gaza. Afterwards, three more House Democrats called on Biden to drop out of the race. Other Democrats praised Biden's foreign policy expertise. The second big question in this race is who will former President Donald Trump choose for his running mate?
