The protest comes amid an ongoing legal battle over whether National Guard troops can be deployed in Portland as President Donald Trump ordered.

Tens of thousands across Oregon and Washington — and nationwide — peacefully marched in the "No Kings" demonstrations; Portland police said no arrests were made.

Crowds hit the streets Saturday in cities and towns across the country to vent their anger over President Trump's policies in "No Kings" protests.

At least 40,000 to 50,000 Portlanders took to downtown streets yesterday, Saturday, October 18, to march, wave signs, and raise their voices against the increasingly authoritarian policies of President Trump—though some estimated the crowd size to be much larger.

Portland's waterfront was flooded with tens of thousands of people Saturday for the 'No Kings Rally and March.'

“No Kings” rallies unfolded across the United States on Saturday and reporters and photographers from the parent company of The Oregonian/OregonLive documented dozens of them, from Portland to Boston. The largest of Portland rallies gathered at Tom McCall Waterfront Park and drew 40,000 people, police said.

After multiple orders to disperse, police moved in and made arrests hours after thousands peacefully took to the streets for a "No Kings" protest.
