Democratic presidential candidate Joe Biden is expected to address a recent allegation of sexual assault on Friday. The former vice president has been facing pressure to respond to an accusation made last year by a woman who worked in his office when he was a senator. Tara Reade originally accused Biden of touching her neck and shoulders in the '90s. She later changed her story to include sexual assault. CBSN political reporter Caitlin Huey-Burns joins CBSN's Elaine Quijano with more.
