PORTLAND Ore. (KPTV) - An anti-Trump protest labeled “No Kings” is took place on Saturday in Portland. According to the Portland Police Bureau, the rally drew “tens of thousands” of people to Waterfront Park and wrapped up around 4 p.m. Police did not report seeing any criminal behavior during the event.

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

Organizers say they expect even larger crowds than those that gathered in June to protest the Trump administration's actions. In Maine, rallies are planned for Portland, Lewiston-Auburn, Augusta and dozens of other communities.

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

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

PPB said it has worked alongside agencies like the Oregon State Police, ODOT and TriMet to maintain safety at protests.

With chants, costumes and colorful signs, Washingtonians raised their voices against Trump's hard-line policies on immigration, the federal budget and more.
