A series of Saturday clashes between Antifa and right-wing groups were caught on video and posted to Twitter by journalists Andy Ngo, Elijah Schaffer and others.

Portland’s Rose City Antifa comprised one of the leftist groups there to oppose right-wing demonstrators from various organizations, including Proud Boys, Oathkeepers, and Three Percenters.

President Donald Trump tweeted Saturday morning that the city was “being watched very closely” with consideration “being given to naming Antifa” a terrorist organization.

Major consideration is being given to naming ANTIFA an “ORGANIZATION OF TERROR.” Portland is being watched very closely. Hopefully the Mayor will be able to properly do his job! — Donald J. Trump (@realDonaldTrump) August 17, 2019

TheBlaze reporter Elijah Schaffer documented interactions throughout the day, including Antifa being joined by “about 300 other people from generic liberals, the NAACP, dog fetish sex costumes, the lgbtq community and much much more.” (RELATED: Watch: Antifa Members Condone Violence Against Journalist Andy Ngo)

“I didn’t come to talk, I came to bring it out.” Things are getting tense at the antifa protest. Someone hit a man’s microphone to the ground. I recognize this shirtless man from Seattle last year at another antifa protest. He came up to me and said, “Death is coming.” pic.twitter.com/mzK2i9y5Gl — Andy Ngo (@MrAndyNgo) August 17, 2019

As mob continued to follow the small group going to their cars, a masked antifa person ran up & stole the man’s flag. They mock the group before police finally step in again. They offer to escort the group, which angers the mob. Great footage captured by @TPostMillennial! pic.twitter.com/OMgeLDffkm — Andy Ngo (@MrAndyNgo) August 17, 2019

The aggressive antifa shirtless man who was threatening people was arrested by police. This angered the mob who said this was police bias. #PortlandProtests pic.twitter.com/OYDsyLw3EY — Andy Ngo (@MrAndyNgo) August 17, 2019

Ngo documented an Antifa mob chasing and attacking a man and a young girl who got separated from their group.
