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 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.

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.

"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.

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.
