House Speaker Nancy Pelosi called on Virginia's Democratic governor, Ralph Northam, to resign after an old yearbook photo surfaced that appears to show Northam in racist garb.

"The photo is racist and contrary to fundamental American values," Pelosi D-Calif., tweeted Saturday. "I join my colleagues in Virginia calling on Governor Northam to do the right thing so that the people of the Commonwealth of Virginia can heal and move forward."

Pelosi is among a group of Democrats who have called on Northam to step down.

He has scheduled an afternoon press conference. According to media reports, Northam does not believe he is depicted in the photo and is not planning to announce his resignation.

Northam's page in the 1984 yearbook includes a photo of a person in blackface standing next to someone wearing a KKK hood and robe. Northam had initially acknowledged he was in the photo but did not say which attire he was wearing. He has since reportedly backtracked on that admission.
