Virginia Attorney General Mark Herring shook his state’s already-reeling Democrat power structure Wednesday by disclosing that he wore blackface to a college party in 1980 when he and friends dressed up as popular rappers.

In a lengthy statement released by his office and on Twitter, Herring said he was a 19-year-old student at the University of Virginia when he and friends “put on wigs and brown makeup” to perform at the party “dressed like rappers we listened to at the time, like Kurtis Blow.”   

“This was a one-time occurrence and I accept full responsibility for my conduct,” Herring, 57, said in the prepared statement. “That conduct clearly shows that, as a young man, I had a callous and inexcusable lack of awareness and insensitivity to the pain my behavior could inflict on others.”

“This conduct is in no way reflective of the man I have become in the nearly 40 years since,” he added.

The attorney general’s revelation means that Virginia’s top three elected leaders, all Democrats, are embroiled in controversy.

Herring’s statement comes four days after he called on Virginia Gov. Ralph Northam to resign over the revelation Friday that a photo of someone in blackface and someone wearing Ku Klux Klan robes appeared on his page in his 1984 medical school yearbook.

And Virginia Lt. Gov. Justin Fairfax, 39, who would become governor if Northam stepped down, has become the subject of a public allegation by a woman, Vanessa Tyson, who says he sexually assaulted her during the Democratic National Convention in Boston in 2004. Fairfax has denied the accusation, saying their encounter was consensual.

Fairfax, who is black, criticized Northam for behavior that allegedly occurred 35 years ago while stopping short of demanding the governor resign.

At first, Northam, 59, said he made a mistake by posing for the “racist and offensive” yearbook photo, without saying which person pictured was him. But the next day, Saturday, Northam said neither of those in the photo was him.

“It is no longer possible for Governor Northam to lead our Commonwealth and it is time for him to step down,” Herring said in his statement Saturday on the scandal. “I have spoken with Lieutenant Governor Fairfax and assured him that, should he ascend to the governorship, he will have my complete support and commitment to ensuring his success and the success of our Commonwealth.”

After Fairfax, Herring is next in line to become governor in the event of a vacancy. After Herring, next in line is the speaker of the House of Delegates, Republican Kirk Cox, 61.

Herring, a former state senator, concluded his statement Wednesday by saying:

In the days ahead, honest conversations and discussions will make it clear whether I can or should continue to serve as attorney general, but no matter where we go from here, I will say that from the bottom of my heart, I am deeply, deeply sorry for the pain that I cause with this revelation.
