Protesters burned an American flag and Bibles, sparking outrage as tensions continue to rise in Portland, Oregon.

For more than 60 days, Black Lives Matter demonstrators, including a “Wall of Moms” and a “Wall of Vets,” have drawn national attention for clashing with federal agents in the city.

Friday night’s demonstrations were mostly peaceful, which seemed to be a break from weeks of violent demonstrations. Federal agents made a recent deal to allow local authorities to handle the protests.

Yet, just after midnight, some marchers were caught on camera using the flag and the Bible to begin bonfires outside the federal courthouse. This location has been a central point of rioting following the death of George Floyd, according to KOIN, a CBS affiliate.

“Left-wing activists bring a stack of Bibles to burn in front of the federal courthouse in Portland,” Ian Miles Cheong claimed on Twitter Saturday.

A viral video showed protestors tossing Bibles into a ferocious bonfire.

“Now we move to the book burning phase,” Donald Trump Jr. said in a tweet Saturday. “I’m pretty sure ANTIFA doesn’t actually stand for what they say it stands for. Maybe just remove the anti part of [their] name, and it’s perfect.”

Moms United for Black Lives Matter, later put out the fire, stomping the embers and dousing the flames with bottles of water.
