(AP Photo/Julio Cortez)After meeting last month in perhaps the most chaotic debate in modern history, President Donald Trump and his Democratic rival, Joe Biden, will take the stage Thursday to give it another go. Biden and Trump instead participated in dueling town halls on competing television networks. CORONAVIRUSSince the last debate, Trump was diagnosed with and hospitalized for COVID-19. Welker will be the first Black woman to serve as the moderator of a presidential debate since Carole Simpson in 1992.

On Thursday, Oct. 22, 2020, Welker is scheduled to moderate the second and last Presidential debate between President Donald Trump and Democratic presidential candidate former Vice President Joe Biden. The NBC News White House correspondent is scheduled to moderate Thursday's second and last session between Trump and Democrat Joe Biden. While Welker was one of four questioners at a Democratic presidential debate last fall, this is by far the 44-year-old journalist's biggest stage. She's the first Black woman to moderate a presidential debate since Carole Simpson in 1992. Andrea Mitchell, the NBC News correspondent who moderated last fall's Democratic debate with Welker, Rachel Maddow and Ashley Parker, doubted her colleague would be intimidated.
