Thousands are expected to take to the streets of Portland on Saturday as the second "No Kings" protests this year kick off across the country. Why it matters: The latest round of protests comes amid growing frustration about the government shutdown and widespread opposition to President Trump's military crackdown on Democratic-led cities across America,

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.

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.

The scene outside the ICE facility took a darker turn as federal agents deployed tear gas on the crowd around 4:30 p.m. and detained at least one person over the course of the next hour.

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