Millions of Americans are expected to join over 2,600 'No Kings' protest events across all 50 states on Saturday, demonstrating against President Donald Trump's policies on immigration, education, and security. The protests, organized by progressive groups and supported by high-profile politicians and celebrities, aim to push back against what organizers describe as a drift toward autocracy. Organizers have provided legal and de-escalation training for marshals, and social media campaigns have driven turnout. Republican leaders have criticized the rallies, labeling them as anti-American, while experts predict this could be one of the largest protest mobilizations in modern United States history.
