Vice President Kamala Harris has expressed her support for President Joe Biden following his widely panned debate performance last month and is "increasing her role" in the campaign ahead of the election this November, Cedric Richmond, co-chair of the Biden-Harris campaign, told MSNBC's "The Sunday Show with Jonathan Capehart."

Richmond, a former congressman from Louisiana, said Harris "is increasing her role, and she's been a valued partner since day one. I won't get into whether she's been covered fairly by the press, but she is a valuable partner."
