“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.

Portland, Oregon is preparing for more violence between the right-wing group Proud Boys and leftists from Antifa - a group of black-clad left-wing extremists who have instigated several bloody brawls with conservatives.

Police learned of the unlicensed protest and the Antifa counter-protest by monitoring social media, according to NBC News, which notes that based on what has been observed, there is concern over possible violence (where masked 100lb basement-dwelling Antifa soy boys get knocked into the next dimension).

In recent years, Portland has become a magnet for protests, some of them turning ugly. Several groups from the far-left and far-right said they will converge in the city's downtown. Police said its nearly 1,000 member force will be on duty.

"We recognize these events can cause alarm, anxiety and even fear for certain members of our community," said Lieutenant Tina Jones. -NBC News

Last year:

In a Saturday tweet, President Trump put Portland Mayor Ted Wheeler on notice.

"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!"

"I think they come to Portland because it gives them a platform," said Wheeler of why right-wing groups are protesting in Portland. "They know that if they come here conflict is almost guaranteed."

In 2017, a riot between the groups left the city with shattered windows and other property destruction.

"It's sad to me because I think that a lot of people that come here to protest don't actually live here or share a lot of values that I believe Portland stands for," said resident Drew Edwards.

The FBI will be on scene out of an abundance of caution, reports NBC.
