 As there are calls from fellow Democrats to exit the presidential race, President Biden plans to host a high-stakes news conference today. It comes after the president's interview with ABC News did little to ease concerns over whether he could defeat Donald Trump and serve another term. The event comes as the New York Times reports the Biden campaign is testing how Vice President Harris would match up against Donald Trump in the general election. The House minority leader says his fellow Democrats are having ongoing discussions about President Biden's candidacy. Liz Warner reports.
