PORTLAND, Ore. — Portland police made two arrests during planned protests Sunday, including a downtown march and a demonstration outside the federal immigration facility in South Portland, as tensions grow over a new legal battle between Oregon and the Trump administration.

During an otherwise peaceful gathering, police "observed some physical fights between participants with opposing viewpoints," and arrested a 17-year-old male on fourth-degree assault charges. The young man was from Milwaukie, Oregon.

A second arrest was made around 10 p.m. Portland resident Nathan McFarland, 38, was arrested on a third-degree assault charge. Officers are also investigating a property crime nearby, the bureau said.

According to a statement from the Portland Police Bureau (PPB), the city deployed extra officers and public safety teams Sunday, warning that at least one march would impact traffic downtown. Additional police were assigned to patrol near the U.S. Immigration and Customs Enforcement (ICE) building.

The police presence came on the same day Oregon Attorney General Dan Rayfield announced that the state of Oregon and city of Portland had filed a federal lawsuit against the Trump administration, alleging that President Donald Trump unlawfully ordered the deployment of 200 Oregon National Guard members for federal law enforcement duties.

In a statement, PPB said its officers do not participate in immigration enforcement but are still responsible for enforcing state law and maintaining safety. Officers on bikes, motorcycles, and in patrol units were posted around protest areas. Police also deployed liaison officers, whose role is to communicate with demonstrators.

An Incident Command Team was activated to oversee the response, which includes sound trucks and an air support unit. PPB said officers may appear in large groups to respond to specific incidents or make targeted arrests but stressed that not all enforcement actions happen during the protests themselves.

The bureau said follow-up investigations may result in charges being filed after events conclude.

PPB Chief Bob Day discussed the activity at the ICE facility during a news conference Monday afternoon.

"Political violence is not acceptable. Violence in the city is not acceptable, and I'm super proud of where we have come in the last couple of years around public order events as well as in the reduction of crime, but we will not accept or tolerate people coming down to South Waterfront for the purpose of engaging in violence," Day said.

PORTLAND, Ore. — Thousands of people marched across the Burnside Bridge from downtown Portland on Monday afternoon in a culmination of protests against the Trump administration and Labor Day rallies.

Multiple political rallies were planned around the Portland metro area Monday — some of which are billed as "Workers Over Billionaires," part of a coordinated nationwide series of Labor Day protest events. Some of the events were being organized and promoted by the same groups behind a series of anti-Trump protests that have drawn thousands of people to downtown Portland this summer.

The downtown Portland protest began at noon, meeting at the Battleship Oregon Memorial in Tom McCall Waterfront Park. After the initial rally, the march began down and across the Burnside Bridge, heading south and then back across the river via the Morrison Bridge.

Marchers reached the Morrison Bridge around 2 p.m. and the bridge was clear again by 2:30 p.m.

TriMet also issued an alert earlier in the afternoon warning riders that downtown protests could disrupt MAX service.

The organizers bill the protest as a rally to "reject the systematic dismantling of our democracy" and demand the removal of the Trump administration.

"This administration is threatening the rights of women, immigrant rights, rampant inflation, targeting of trans communities, Gazan lives, and gutting our democracy," the organizers wrote in an announcement. "The reality of this situation is we cannot win any of these battles while Trump and his administration remain in power. The solution and our demand? Remove Trump."

This is a developing story and may be updated with more details as they emerge.

PORTLAND, Oregon — The Cottonwood School of Civics and Science relocated, just weeks before the school year begins Sept. 2.

The decision to move followed months of protests outside Portland's U.S. Immigration and Customs Enforcement facility and law enforcement's response to the demonstrations, which raised safety concerns.

The K-8 charter school had been next door to the ICE building for years. But interim Executive Director Laura Cartwright said increased protest activity at the facility this summer led to the use of chemicals and munitions that went onto school grounds, and it made the site unsafe.

"At the end of the school year, we started noticing more activity at the ICE building, and there were chemicals being used on a regular basis and munitions being found on our playground," Cartwright said.

During the summer, it got worse.

"Our garden was enveloped in gases one evening, and we started to think we might not be able to mediate this in the school year and open on time," she said.

Cartwright said school officials had to remove wood chips, clear and test the soil, and complete other cleanup work before and after the 2020 protests. However, as kids weren't coming back to school full time back then due to the pandemic, this time was different and harder to navigate.

The school director said enrollment also began to drop as parents told the school they weren't going to send their children back because of the school's proximity to the ICE facility.

"We are chartered to be able to have up to 220 (students); however, we are at 157 right now, for all the loss of enrollment over the summer due to the activity," Cartwright said.

Earlier this month, the school board approved a move to Southwest First Avenue, where Cottonwood is subleasing the building Bridges Middle School was originally housed in, which moved into a different, permanent building recently.

Portland city officials helped coordinate the transition.

"What made this work is we did build some partnerships between the two different schools, our internal bureaucracy, other council offices and just got everyone on the same page," said City Councilor Mitch Green, who represents District 4.

"One of the things that we realized pretty early on was that we have a really effective Portland Permitting and Development department," he also said. "We brought them in pretty early, and kind of pulled together all the partners of the schools, pulled my team into it, and just came up with a plan to tackle this pretty quickly."

He said this was all done within a month and a half.

His office has also helped coordinate a volunteer opportunity for other city council staff to help as well, and he will be helping with setting up the school this weekend as well.

"I'm feeling really hopeful," Cartwright said. "Our community is really resilient."

Cottonwood is continuing to raise money and collect donations to support the move. Anyone wishing to support can do so here.

PORTLAND, Ore. — Three defendants made their first appearances in court on Thursday, federal prosecutors said, after allegedly committing crimes during ongoing protests outside of the U.S. Immigration and Customs Enforcement (ICE) facility in South Portland. One of them is accused of throwing a knife at federal officers.

The demonstrations have been ongoing for several weeks as a response to ICE arresting and detaining undocumented immigrants, and they're part of a larger, nationwide movement. At times, the situation has escalated, as captured on video Tuesday night, leading to serious action and criminal charges.

Video shared this week with KGW shows Federal Protective Service officers follow and use a Taser on a woman after they said she attempted to light an incendiary device, waved a large knife at them, and threw it at one of the officers. When two people tried to set an American flag on fire, according to officials, the federal officers used gas canisters to disperse the crowd, leading to this escalation.

Court documents named the woman as 46-year-old Julie Winters. She faces a charge of attempted assault of a federal officer, which is a felony. Two others people, 20-year-old Aziel Chambers and 28-year-old Rachel Pope, also made their first appearances in federal court on Thursday.

KGW spoke with some of the demonstrators who peacefully gathered outside the ICE building on Thursday afternoon. Some said the headlines and arrests are not telling the full story. 

"This is literally a bunch of community members coming together and providing support for marginalized people, that's what they're not seeing," said one activist. "It's mutual aid, which I honestly thought that was Portland values. I thought that was the progressiveness of it, but I'm seeing it being criminalized."

Neighbors have observed interactions between federal officers and protesters for weeks. 

"Like, are we a third world country right now?" Mindan Ocon said. "Like, why are you, you know, attacking civilians like that and protesters? I understand, you know, there is a couple of protesters who get mad and do what they want to do, but don't take that away from the protesters who are peaceful."

In a statement, Department of Homeland Security Assistant Secretary Tricia McLaughlin said, in part, "Unfortunately, these violent attacks are becoming more and more common... Secretary Noem's message to the rioters is clear: you will not stop us or slow us down. ICE and our federal law enforcement partners will continue to enforce the law. And if you lay a hand on a law enforcement officer, you will be fully prosecuted of the law."
