Thousands of 'No Kings Day' protests are expected to take place across the nation Saturday, with the 'flagship' protest planned for Philadelphia.

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 a city known as the cradle of American democracy, an impassioned, hourslong protest filled the streets for a ‘No Kings Nationwide Day of Defiance.’

Philadelphia will be the site of a “flagship protest” in a nationwide movement opposing President Donald Trump’s Administration on the same day as a major military parade in Washington. The demonstration is expected to disrupt traffic throughout the day.
