 From the ABC News desk, later today, President Biden will hold a news conference as he faces calls from some Democrats to drop out of his reelection bid. The news conference is scheduled for 6.30 p.m. This comes after the president's interview with ABC News did little to ease concerns over whether he can stand to defeat Donald Trump and serve another term. Biden struggled to answer questions during the last month's debate, sparking worries about the president's mental capacity.
