Shortly after 9 p.m., officers tackled protesters and detained them as the crowd of several hundred people yelled at them. Police told protesters to move back and get out of the street as they made the arrests.

Protesters chanted: “No good cops in a racist system!”

Protesters shot fireworks at police. KOIN-TV posted a video in which police warn that protesters who hurl projectiles will be subject to arrest.

About 10 p.m., police left the scene. The protesters remained in the street.

Earlier Saturday police said a right-wing rally and counter-protests largely dispersed without serious violence, though they are investigating an assault after one person who was documenting the event was pushed to the ground and kicked in the face.

Separately, police said a criminal citation was issued after officials confiscated firearms, paintball guns, baseball bats and shields from a pick-up truck that was initially stopped for having obscured license plates as it left the rally, AP reported.

Several hundred people, dozens of them wearing militarized body armor, gathered to support US President Donald Trump and his “law and order” reelection campaign Saturday afternoon. The attendance was far fewer than the 10,000 organizers had expected after tensions boiled over nationwide following the decision not to charge officers in Louisville, Kentucky, for killing Breonna Taylor.

Organized by the Proud Boys, a group that has been designated as a hate group by the Southern Poverty Law Center, the rally was described as a free speech event to support Trump and police and condemn anti-fascists and “violent gangs of rioting felons” in the streets.

Local and state elected officials condemned the event and rushed to shore up law enforcement ranks as left-wing groups organized several rallies to oppose the Proud Boys’ message. About 1,000 counter-protesters gathered at another park.

The events began at noon and were largely dispersed by 3 p.m.

The rally came as Portland has seen nearly nightly protests since the police killing of George Floyd in late May.

“My Administration will not allow Federal tax dollars to fund cities that allow themselves to deteriorate into lawless zones,” said the memo, which was released by the White House, Reuters reported.

The memo instructs Attorney General William Barr to develop a list of “anarchist jurisdictions” that “permitted violence and the destruction of property to persist and have refused to undertake reasonable measures” to restore order.

The memo also instructs White House budget director Russell Vought to issue guidance in 30 days “to the heads of agencies on restricting eligibility of or otherwise disfavoring, to the maximum extent permitted by law, anarchist jurisdictions in the receipt of Federal grants.”

New York Governor Andrew Cuomo said on Twitter that Trump was trying to cut off funding that states and cities must receive to recover from the coronavirus pandemic.

“He is not a king. He cannot ‘defund’ NYC,” Cuomo said. “It’s an illegal stunt.”

Most in the recent group wore helmets, reflective vests or shirts emblazoned with the word “PRESS” and had media badges dangling from their necks. But some were demonstrators, taking cover behind reporters despite orders to go home or face arrest.

“Hey,” an officer yelled at his colleagues as they cleared streets and arrested people who weren’t leaving. “Half this group is not press. … Purple mask isn’t press. Bicyclist not press. … If they are not press, take them into custody.”

For nearly 100 days, reporters have been covering protests that often turn violent in Oregon’s largest city, and in the chaos, some journalists have been injured or arrested despite press freedoms laid out in the First Amendment. The clash also led to a lawsuit against federal authorities sent in to help local police in July.

Reporters — whether they’re from major media outlets, freelancers or self-proclaimed “citizen journalists” — say they are doing their job and law enforcement is hindering that work. Police say protesters have masqueraded as journalists and then set fires or thrown fireworks, making it a struggle to figure out who is a real reporter during the pandemonium.

Suzette Smith, a freelance journalist who has covered the protests, recorded the Aug. 29 encounter between police and reporters. “Blue mask,” an officer could be heard saying in the video Smith tweeted. Her mask was blue, and she held up her press badge. At least five people around her were detained, including someone else in a blue mask.

Smith, who was arts editor of the Portland Mercury alternative newspaper but was laid off during COVID-19 pandemic, said it was the first time she has seen officers approach a crowd of journalists and arrest people around her. But protesters will stay behind reporters to try to blend in, she said.

“Certainly that’s annoying as a press person when there is somebody behind you yelling,” Smith said. “I have definitely asked them not to yell in my ear or to stand so close.”

Sergio Olmos, a reporter for Oregon Public Broadcasting, has been covering the Portland protests for months and has reported from other demonstrations in the city and civil unrest around the world. He said reporters have been treated differently during protests over the police killing of George Floyd in Minneapolis.

Olmos said police went from viewing reporters as professionals and neutral observers to demonstrators. While covering Portland’s protests, he says he has been pushed to the ground by police, hit in the lip with a baton and tear gassed.

“(Journalists) who stay out there have made a mental commitment of ‘I might get beat or I might get arrested, and that’s just the cost of doing this job I guess,’ ” Olmos said.

According to the US Press Freedom Tracker, made up of more than two dozen press freedom groups, over 740 aggressions against journalists have been reported during national Black Lives Matter protests this year. That can include attacks, arrests or equipment getting damaged, searched or seized.

“What really has been striking about these weeks of protests is that there has not just been one incident that stands out,” said Kelly Simon, interim legal director of the American Civil Liberties Union of Oregon. “It is such a high volume of concerning abuses of our constitutional rights, that there is no way we can sit on the sidelines.”

In July, the ACLU of Oregon sued Portland police and federal agents on behalf of a group of legal observers and journalists. A freelance photographer covering the protests for AP submitted an affidavit saying he was beaten with batons, sprayed with chemical irritants and hit with rubber bullets.

A federal judge granted a preliminary injunction exempting journalists and legal observers from orders to disperse after authorities declare a riot. But an appeals court later suspended it.

Police report that people with “press markings” have thrown commercial-grade fireworks, rocks and bottles at officers over the past two months and mingled with people in the crowd. In mid-August, police said an officer was seriously injured after a person with “press” on their clothing threw a 9-pound rock.

Police declined requests for an interview. In a June video, Lt. Tina Jones said Portland police “continue to work with our media partners about the importance of following the lawful orders given by the sound truck, officers and social media so they can stay safe and avoid arrest and altercation.”

While many reporters clearly identify themselves, officials have discussed if more can be done.

US District Judge Michael Simon suggested redefining a journalist as “someone who is authorized by the ACLU,” saying the organization “could maintain a list of who they are giving vests to and give them appropriate guidance and instructions. That way we might be able to solve the problem of somebody just putting ‘press’ on their helmet or their shirt.”

Media experts say it’s broader than that.

“Who is a journalist and who isn’t a journalist? Well, here is my definition: You are a journalist if you are committing journalism — if you are there at the scene of the news to collect information and present it to an audience in journalistic form,” said Patricia Gallagher Newberry, national president of the Society of Professional Journalists.

On the 96th consecutive night of demonstrations in Oregon’s largest city since the killing by police in Minneapolis of an unarmed black man sparked protests across the nation, around 200 people marched to the apartment where mayor Ted Wheeler lives, the Independent reported.

Wearing black hats to “celebrate” the mayor’s 58th birthday, people stood in the street and demanded that he resign, complaining that he had failed to reform the city’s police force.

At least one window was broken and a firework was reportedly set off in the building. Someone also dragged a picnic bench to the intersection and set it on fire.

Shortly afterwards, officers from the Portland Police Department (PPD) moved in, using loudspeakers to declare a riot and warning people to disperse or else face arrest.

“This was the arson fire that prompted a riot declaration tonight,” the PPD wrote on Twitter, of an image of the blaze. “It was critical to secure the area to allow firefighters to respond to this dangerous situation.”

One protesters, who asked to use the initials FO, was using a loud hailer to call on Mr Wheeler to resign and the police officers to quit as well.

“They need to quit, and they need to defund the police,” she said.

Events on Monday night were just the latest flare-up in Portland, a Democratic-controlled city which has been attacked by Donald Trump and his supporters as an alleged hot bed of anarchy.

“Portland has been burning for many years, for decades it’s been burning,” he told Fox News.

The Portland protesters so far were peaceful, with demonstrators chanting “take it to the streets!”

But on Saturday afternoon a rally by a small group of alt-right demonstrators quickly devolved as they traded paintballs and pepper spray with counter-protesters.

About 30 people were participating in the Patriot Prayer rally in front of the Multnomah County Justice Center in Oregon’s biggest city. Several were armed with automatic weapons, KOIN-TV reported.

The group clashed with counter-protesters through downtown streets, and some counter-protesters blocked the exit of a garage where several Patriot Prayer members had parked.

A KOIN photojournalist reported hearing at least two gunshots at the garage.

In an emailed statement Saturday, Portland Police Sgt. Kevin Allen said the bureau was not aware of evidence that there was gunfire, AP reported.

Earlier in the day, police said they made four arrests overnight as they dispersed a protest that was headed toward the offices of the police union.

The bureau declared the demonstration of a couple of hundred people an unlawful assembly Friday night, saying people were throwing fireworks, golf balls, and chunks of concrete at officers. Officers said they used crowd-control munitions but no CS tear gas to disperse the crowd.

Demonstrations, often violent, have happened nightly in Portland for more than two months following the killing of George Floyd by Minneapolis police. Participants have repeatedly broken into the offices of the Portland Police Association, vandalized them, and set fires.

A vigil for George Floyd, the man killed by Minneapolis police, descended into violence on Friday night in Portland, Oregon. The protesters targeted the Multnomah County Justice Center, which houses the sheriff’s office and detention center in Portland. In videos posted to social media, protesters are seen breaking windows and setting fires inside the building. One clip shows a group of protesters smashing computers and overturning desks and furniture, RT reported.

Protesters can be heard shouting “burn that s**t down” as flames rise from the building’s windows.

Portland Police have declared the protest a riot and warned all demonstrators to vacate the area or be subject to “gas, projectiles, and other means necessary for dispersal.”

Riots and protests have sprung up in cities across the United States. The Pentagon is reportedly preparing to send military police to Minneapolis, while several states have already mobilized their national guards.
