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

Millions of people turned out for "No Kings" protests nationwide on Saturday that were largely peaceful though there were some arrests and police had to disperse unruly crowds, including in Georgia and Los Angeles.

In the Greater Boston area, thousands of “No Kings” marches and rallies are taking place, part of major demonstrations planned across the country.
