The leaders of a Portland activist group formed after Donald Trump's election have organized a fundraiser to repair the damage caused by rioters Thursday night.

In a news release posted to Facebook, the newly formed protest group Portland's Resistance said the property damage caused by Thursday's riot "had absolutely nothing to do with our group" but was caused by a separate band of protesters.

Many demonstrators were trying to get protesters from a separate anarchist group to stop destroying property but they refused, Portland police said Thursday night. Police spokesman Sgt. Pete Simpson told the Washington Post that the peaceful protest was "infiltrated" by anarchists.

Leaders of Portland Resistance, which was one of the groups organizing the peaceful protesters, are partnering with Latino civic organization Milenio to raise money to repair, they said Friday morning. They also set up a GoFundMe page, which had raised more than $13,000 as of Friday afternoon.

In their release, leaders apologized to anyone whose property was damaged, though it was not done by their group, they said. They added that the group doesn't condone violence, but they emphasized that vandals could have participated because they feel unheard and "destruction is their only voice." The group said it will continue to focus on goals it has outlined for Portland, including rent control, citizen oversight of police and better school funding.

"We made it very clear that ours was a movement born out of love, infused by peace and inhospitable to those that would put us all at risk in the name of actions that are inflammatory, divisive and strategically ill-conceived. That remains our goal," the group said.

Portland Resistance, which organized after Donald Trump won the 2016 presidential election, peacefully marched in Portland for the past three nights in protest of the election. Spokesman Gregory McKelvey said the group will use anti-Trump efforts to bring attention to local movements.

Police declared the demonstration a "riot" at about 8 p.m., citing "extensive criminal and dangerous behavior." Rioters broke windows on businesses and vandalized cars at a dealership. Some threw bottles and shot fireworks. Police estimated more than $1 million in damage was inflicted; 25 people were arrested.

On Friday morning, a separate group of volunteers, organized by Portland Community College student Jacob Dahlberg, cleaned up trash and graffiti along the protest route. Dahlberg organized volunteers by creating a Facebook event, which Portland Resistance shared. Dahlberg and 10 other volunteers also gathered contact information for businesses affected by the protest, which they will pass on to Portland Resistance leaders so they can distribute money from the GoFundMe effort, Dahlberg said.

Dahlberg said more people interesting in volunteering are contacting him. He organized the event to "show that no matter what happens, people will have the community to rely on," he said.

Portland Resistance said it will hold a rally and "heal-in" at Portland City Hall to discuss their demands for the city and campaign to repair damage from Thursday night. The rally will begin at 5 p.m.
