The "No Kings" protest and march happening in Philadelphia on Saturday coincides with hundreds of rallies scheduled to take place across the country.

The "No Kings" protest is taking place in cities across the country in response to Trump's military parade in Washington, D.C.

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.

Thousands are expected to pack the parkway for the "No Kings" protest. Organizers said they believe Philadelphia's demonstration will be among the largest in the country.

Protesters in Philadelphia are slated to hit the streets Saturday, just days after 15 anti-ICE demonstrators were arrested following a skirmish with police officers in Center City. The protest in Philadelphia is part of a nationwide “No Kings” action planned by critics of President Donald Trump’s administration,

Philadelphia’s "No Kings" protest was a mass expression of anti-Trump resistance. It was also a magnet for lovers of period costumes. The rally featured a professional James Madison impersonator, a suffragette and an array of folks in wigs and tricorn hats.
