Democratic Virginia Gov. Ralph Northam's medical school yearbook page featured a picture of a man in blackface standing alongside a man in Ku Klux Klan robes, it was reported Friday.
NBC has not obtained a copy of the yearbook, and is not aware of the identities of the men in the picture in blackface or the Klan robes.
Northam's office had no immediate comment on the photo.
"Racism has no place in Virginia," said Republican Party of Virginia chairman Jack Wilson. "These pictures are wholly inappropriate. If Governor Northam appeared in blackface or dressed in a KKK robe, he should resign immediately."
Northam came under fire from Republicans earlier this week, who accused him of supporting infanticide because of comments he made about late-term abortions in which the infant is severely deformed or unable to survive after birth.
The yearbook photo was first reported by a website called Big League Politics, a far-right site that often promotes conspiracy theories.
