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.’

Thousands gathered in Daley Plaza and in suburban events in protests timed to coincide with a military parade in Washington celebrating the Army's 250th anniversary and President Donald Trump's 79th birthday.

Tens of thousands of Americans joined "No Kings" protests across the United States against the Trump administration.

"No Kings" rallies brought demonstrators together, joining voices across the nation and region to protest what they call a growing threat of authoritarianism in American politics.

As many as 2,000 protests are planned across the country. Organizers say they’re meant as a counteraction to Trump’s lavish parade, which also happens to fall on his birthday.

Coordinated "No Kings" protests are underway from coast-to-coast, part of a "national day of peaceful protest" against the Trump administration that is expected to draw millions. Protesters in some areas braved wet weather to raise signs and chant slogans supporting the rights of immigrants and criticizing what they see as Trump's power grab.
