We discuss the history behind calls for Democratic Virginia Governor Ralph Northam to resign after a photo surfaced on his 1984 Eastern Virginia Medical School yearbook page showing a man wearing blackface posing next to a man wearing a Ku Klux Klan outfit. The yearbook also features an image of a white man in a wig, dress and black face. The photo’s caption reads, “'Baby Love,' who ever thought Diana Ross would make it to Medical School!” Another photo in the yearbook shows three men in blackface. We are joined by Rhae Lynn Barnes, assistant professor of American cultural history at Princeton University and author of the forthcoming book “Darkology: When the American Dream Wore Blackface.” Her new article for The Washington Post is headlined “The troubling history behind Ralph Northam’s blackface Klan photo.”
