A teenage girl in California was brutally beaten — allegedly because she supported Donald Trump — in an attack caught on cellphone video, police said Monday.

Jade Armenio, a sophomore at Woodside High School, 30 miles south of San Francisco, was thrown to the ground, punched and kicked by another girl Wednesday in disturbing footage that’s gone viral.

The attacking student has been suspended and the scary beatdown is being investigated by off-campus cops. No one has been arrested yet.

“We have an open dialogue with the parents (of the students) involved (in the beating) and the school,” San Mateo County Sheriff’s Detective Sal Zuno said Monday. “There might be all sorts of motives (involved in the attack).”

The girl, whose family supports Trump, was allegedly targeted because she responded to a social media thread that started with a post supporting the president-elect.

Jade wrote “one of the few things we can agree on” after someone had responded with a disparaging comment about Mexicans, according to the San Jose Mercury News.

“This girl comes up to me and she said, ‘Do you hate Mexicans?’ and I was like, ‘no,’ and she said, ‘You support Trump. You hate Mexicans,’ ” Jade told KGO.

Todd Armenio insisted his daughter’s “we can agree on” comment was about the original pro-Trump message and was not an anti-Mexican slight.

“She would never do that. We don’t raise our kids like that,” Todd Armenio said.

Jade suffered a bloody nose, scratches and bruises.

The injuries might have been worse if fellow student Breanna Broussard hadn’t come to Jade’s defense. She jumped on top of Jade and shielded her from raining blows.

Broussard could be heard in the video screaming, “Let go of her! Get off her!”

“Nobody deserved to be hurt and harassed the way she (Jade) was,” Broussard told KRON.

The brawl is indicative of simmering racial tensions on the campus that’s about 50 percent Latino and 30 percent white, Broussard said.

“I do think that they (Latinos on campus) are not treated as well as everyone else is,” the student said.
