Vice President Kamala Harris joined a call with major Democratic donors Friday afternoon to discuss what the hosts called "urgent, emerging needs." The call came as more Democratic lawmakers publicly call on President Joe Biden to drop his bid for reelection. A Biden campaign official told NBC News that the president's advisers asked Harris to do the call, which Democratic megadonor Reid Hoffman, the billionaire LinkedIn co-founder, planned to join. "We continue to find ourselves in a rapidly evolving environment," an invitation for the call said. "With the stakes as high as they are this cycle, we have to remain focused on the critical work that needs to be done to protect our democracy."
