Millions of demonstrators took to the streets in more than 3,000 cities and towns across the United States on Saturday as part of the latest wave of “No Kings” protests opposing President Donald Trump and his administration’s policies.

Organizers said the nationwide turnout could reach as high as 8 million people, potentially making it one of the largest coordinated protest movements in U.S. history.

The demonstrations were organized by the National No Kings Coalition and allied groups, who say the protests are aimed at confronting what they describe as ongoing instability and controversial policies under the Trump administration.

Protesters cited a range of grievances, including the expanded use of federal agents for immigration enforcement and the fatal shootings of Renée Good and Alex Pretti in Minnesota earlier this year. Both incidents—where U.S. citizens were killed by federal immigration agents—sparked nationwide outrage and ongoing investigations.

Participants also pointed to the administration’s military campaign involving Iran as another key issue driving opposition.

Leah Greenberg, co-director of Indivisible, one of the coalition’s organizing groups, said the protests are part of a broader strategy to sustain grassroots engagement. She emphasized continued efforts such as monitoring immigration enforcement, supporting affected communities, opposing the war, and expanding voter registration initiatives.

Organizers say the movement is intended not just as a one-day demonstration, but as the foundation for ongoing political mobilization at the local and national levels.
