Huge crowds rallied on Saturday against US President Donald Trump from coast to coast, venting their fury over what they see as his authoritarian style of governing, his hardline immigration policies and the war with Iran.

It is the third time in less than a year that Americans have taken to the streets as part of a grass-roots movement called “No Kings”, the most vocal and visual conduit for opposition to Trump since he began his second term in January 2025.

Organisers say they expect millions to flood the streets of big cities and small towns, demonstrating against everything from immigration raids and high consumer pricing to the war against Iran that Trump launched alongside Israel.

In New York, America’s most populous city, tens of thousands of demonstrators rallied, including Oscar-winning actor Robert De Niro, a frequent Trump critic, who called the president “an existential threat to our freedoms and security”.

Protests unfolded from Atlanta to San Diego, with Alaskans due to join the mix later in the day.

“No country can govern without the consent of the people,” 36-year-old military veteran Marc McCaughey said in Atlanta, where thousands turned out.
