A crowd of roughly 100 protesters faced off Monday with police on the sidewalk in front of the Edith Green-Wendell Wyatt Federal Building in downtown Portland and several people were detained by officers in riot gear.

The protest, organized by Don't Shoot Portland, drew supporters of a number of different causes for a "Not My Presidents Day" rally in protest of Donald Trump. Police lined up facing the protesters, who blocked traffic on Southwest Third Avenue, across from Terry Schrunk Plaza.

Bike-mounted officers pushed the crowd out of the street and a standoff ensued, with police in riot gear keeping the protesters to the sidewalks. Then, as the protesters stood by and chanted, police charged in and grabbed several people, dragging them from the crowd before they were handcuffed and put in waiting police vans.

It was unclear how many people were arrested or what charges they might face.

The remaining group marched through the streets toward Director Park, where a larger rally was already underway. The second rally -- We The People: Marching in Resistance -- gathered a number of groups, including Basic Rights Oregon, Unite Oregon and the Northwest Oregon Labor Council, to "stand in solidarity against attacks on the rights of immigrants, refugees, workers, people of color and the LGBTQ community."

The event was one of four permitted events across the state, also in Eugene, Medford and Salem.

"We want all people who are in our community to feel they have a unified movement behind them," Kayse Jama, executive director of Unite Oregon and spokesperson for the event, said. "I think it's time to take action. Those who have privilege have to put it on the line and defend those who have been targeted. We want to remind people what's at stake, which is the value of our country and make sure we push back."

After a number of speeches, a large group again took to the streets, marching west along Taylor Street, then south along 11th Avenue, before turning northward on Park Avenue and returning to Director Park. That march had permits from the city, Portland police said, and there were no one was arrested.
