Massive demonstrations against President Donald Trump occurred globally, primarily in the United States, on Saturday, organized under the "No Kings" movement. Protesters voiced opposition to Trump's governance style, immigration policies, and the conflict with Iran. Organizers reported approximately 8 million participants at over 3,300 events across all 50 states, with significant rallies in New York, Atlanta, and Washington D.C. This marked the third major "No Kings" protest since January 2025. International solidarity was evident with protests in European cities like Paris, Amsterdam, Madrid, and Rome, where 20,000 marched in Rome. The movement, which began in June 2025, has seen increasing participation with each event.
