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. Note: This map shows protests that have been confirmed and is not comprehensive.
