The college professor who accused Virginia Lt. Gov. Justin Fairfax of sexual assault spoke at a #MeToo symposium Tuesday night — where she was greeted with a standing ovation.

Vanessa Tyson — who last week publicly accused Fairfax of forcing her to perform oral sex on him 15 years ago — appeared before an audience of around 100 people at Stanford University in California, with many others gathering to watch via a video feed in a nearby room.

The Scripps College professor didn’t directly address her allegation against Fairfax, but did talk about students who’d confided in her about their own assault experiences, adding that “sometimes you have to lead by example. No matter how hard it is.”

“When women and survivors start comparing notes — that’s when the light bulb goes off,” she told the crowd, according to a CBS report. “This has been happening to everybody. That’s the most important part of #MeToo.”

Tyson also recalled watching Christine Blasey Ford testifying on her own sexual assault allegations during Supreme Court Justice Brett Kavanaugh’s confirmation hearing last year.

“As she shook, we shook with her,” she said. “As she told her story, we felt the pain she so visibly demonstrated.”

Tyson has hired the same law firm that represented Ford — while Fairfax has recruited the legal team that repped Kavanaugh.

Tyson says she met Fairfax at the 2004 Democratic National Convention in Boston, where she accompanied him to his hotel room one afternoon and “consensual kissing quickly turned into a sexual assault.”

After Tyson came forward, a second woman, Meredith Watson, last week accused Fairfax of raping her in 2000 when they were both students at Duke University.

Fairfax claims both encounters were consensual.

The allegations emerged amid calls for Virginia Gov. Ralph Northam to resign over a racist photo on his 1984 medical yearbook page. If Northam steps down, Fairfax will inherit his job.
