Every group allied with the governor, from Planned Parenthood to the state Democratic party and Democratic leadership in the General Assembly urged Northam to leave office. However, he said he was the only person who could have submitted the family photos that appeared on his own page.
But he said he did darken his face during a dance contest in 1984 when he was 24, the same year he graduated and the yearbook was published.
The page also included Mr Northam's full name and other photos of the politician. I accept his apology and I stand by Governor Ralph Northam.
Kamala Harris (D-CA) said the "stain of racism should have no place in the halls of government", while Sen. The Ku Klux Klan is a terrorist organization.
Not only was this false, but the mistake is insulting to Virginia Republicans who remember the 2017 election in which Northam won the governorship.
Homan also apologized for "past transgressions of your trust".
"Governor Northam must end this chapter immediately, step down, and let Lt. Gov. Justin Fairfax heal Virginia's wounds and move us forward", they said on Twitter.
Should Fairfax become the new governor, this Philadelphia Inquirer columnists says the new governor "supports expanding health care, a higher minimum wage, and would be a FANTASTIC governor. That is not the same as deserving the confidence bestowed in our elected officials", tweeted Guy Cecil, the chairman of Priorities USA. Fairfax's statement does not directly call on Northam to resign. The photo was on Northam's profile page.
McAuliffe and Northam have not talked on Saturday, a source told CNN.
A Republican county official in Pennsylvania, Carla Maloney, resigned previous year due to past social media posts in which she compared kneeling National Football League players to "baboons".
The governor of the U.S. state of Virginia, Democrat Ralph Northam, was embroiled in controversy on Friday, when a racist photo from his university yearbook page was released by an online media outlet.
Northam was scheduled to speak to the public Saturday afternoon. Northam was an adult while attending Eastern Virginia Medical School in 1984. The page shows a picture of a person in blackface and another wearing a Ku Klux Klan hood next to different pictures of the governor.
"It has been discovered that Ralph Northam, governor of Virginia, has pictures in black face and a KKK outfit", Jackson said.
Gov. Ralph Northam is attempting to backtrack, according to The New York Times and The Washington Post. "He should step down and allow the Commonwealth to begin healing", the trio said in a joint statement.
Virginia Gov. Ralph Northam appears to have nearly no choice but to resign after losing support from virtually the entire state Democratic party and other key allies, who urged the governor to leave office because of a racist photo in which he appeared more than 30 years ago.
Northam's statement did not include a response to calls from both Democrats and Republicans that he resign.
