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.

President Donald Trump has responded to planned "No Kings" protests against his leadership, saying "we're not a king at all." Demonstrations targeting him are planned nationwide on Saturday, the same day as a military parade celebrating the U.

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