In Portland, hundreds of demonstrators began assembling outside the Oregon Convention Center around 10 a.m. The crowd grew steadily, with many participants waving flags, banners and signs decrying the president and Immigration and Customs Enforcement.

Tens of thousands of Americans joined "No Kings" protests across the United States against the Trump administration.

Organizers of the “No Kings” demonstrations said millions had marched in hundreds of events. In Oregon, tens of thousands of people gathered in downtown Portland for two large protests -- one that began in Tom McCall Waterfront Park and the other at the Oregon Convention Center.

The demonstrations follow more than a week of large-scale protests in Los Angeles against Mr. Trump’s immigration crackdown and his decision to deploy the military there. Protesters gathered in Liberty Plaza outside of the Georgia State Capitol in Downtown Atlanta.

A nationwide protest is planned on President Donald Trump's birthday to counter a large military parade taking place the same day in Washington, D.C.
