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 "No Kings" protests were scheduled in Connecticut as early as 9:30 a.m. in Canton and Glastonbury and could last elsewhere until 6 p.m.
