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 Philadelphia protest is something of a flagship demonstration amid nationwide actions as Trump holds a controversial military parade in Washington, D.C.

The procession, with more than 6,000 soldiers and 128 Army tanks, was one Trump tried to make happen in his first term.
