RICHMOND, Va. — Virginia Gov. Ralph Northam’s page in his 1984 medical school yearbook contains a photo of a person in blackface and another wearing a Ku Klux Klan hood next to different pictures of the governor.

The photo shows two people looking at the camera — one in blackface wearing a hat, bow tie and plaid pants; the other in white Klan robes. It’s unclear who the people in the picture are, but the rest of the half-page shows photos of Northam beneath his name.

In a statement issued late Friday, Northam apologized for wearing a costume “that is clearly racist and offensive.” The Democratic governor did not say if he was the man in blackface or Klan robes.

“I am deeply sorry for the decision I made to appear as I did in this photo and for the hurt that decision caused then and now,” he said. “This behavior is not in keeping with who I am today and the values I have fought for throughout my career in the military, in medicine, and in public service.

“But I want to be clear, I understand how this decision shakes Virginians’ faith in that commitment.”

Republican state Sen. Bryce Reeves said in a statement that Northam should resign if the reports of the photos are accurate.

“I hope that this picture is inaccurate and that the Governor brings clarity to this issue. This has no place in Virginia,” Reeves said.

If Northam were to resign, Lt. Gov. Justin Fairfax, who is African-American, would assume the governor’s office.
