WATCH: Chaos in Portland as Protesters Clash With Law Enforcement

Sergio Olmos tweeted a series of stunning videos of protesters clashing with law enforcement in Portland.

At least some of the protesters appear to be members of Antifa.

WATCH:

Unlawful assembly declared, crowd at the fence is preparing for police response. Tension high

Standoff at the fence

“Whose streets, our streets” day 8

Consistent with other nights: after tear gas the crowd splits into smaller clusters. This is on main and 6th

Use of force warning, crowd told to leave the area

Crowd forming…a kind of phalanxe

Protestors talking at pioneer square, which has become a kind of “base” after flash points
