A Jewish nonprofit, JewBelong, says two of their billboards in Berkeley, California, regarding antisemitism, have been defaced in the span of just a couple of days.

Archie Gottesman is the co-founder of JewBelong, the nonprofit with billboards in 22 states. She says two of the group's billboards in Berkeley were vandalized this week after someone spray-painted phrases like "Free Palestine" across them.

"I believe in human rights for Palestinians and human rights for Israelis and for peace," Gottesman said.

Gottesman says the group has been in contact with the Berkeley Police Department, investigating the incident as a hate crime.

"It's ongoing, and they'll try and figure it out. I think they're going to be looking at cameras and things like that," she said.

In the Bay Area, antisemitic flyers have popped up in cities like San Francisco, Palo Alto, and Danville.

JewBelong says they remain undeterred and plan on continuing to put up billboards here in the Bay Area and around the country.

"I'm not going to go away because bullies painted over our billboards. We're going to put them up again and come back and be strong," said Gottesman.
