The mother of Heather Heyer, the 32-year-old killed in Charlottesville, Virginia, in 2017 while protesting white supremacy, said Friday she didn’t know beforehand that former Vice President Joe Biden was going to mention her daughter’s death in his 2020 campaign launch video.

“I guess I’m not surprised,” Susan Bro told CNN’s “New Day.” “It seems like Charlottesville has been a defining moment for a lot of people.”

Biden announced his bid for the presidency on Thursday with a taped message invoking the violence that unfolded at the racist “Unite the Right” rally in Charlottesville, where 21-year-old neo-Nazi James Alex Fields Jr. plowed his car into a group of counterprotesters, fatally striking Heyer.

In December 2018, Fields was sentenced to life in prison for her murder.

Biden did not refer to Heyer by name in his video, but noted that “a brave young woman lost her life” in Charlottesville and that she was part of “a courageous group of Americans.” Biden’s campaign video includes footage of white supremacists marching through Charlottesville, carrying torches and chanting “Jews will not replace us.”

Bro told CNN she didn’t realize Biden mentioned her daughter in his video until reporters started calling her that morning.

“It was just sort of a feeling of, ‘Well, here we go again,’ because it’s referred to so often in news articles, stories,” she said. “It’ll show up at the most unexpected moment. I’ll be watching something on TV and there it will be again. So it happens a lot.”
