Millions protested across the US and in Europe against President Trump, criticizing his governance style, immigration policies, and climate change denial. The protests, organized by the grassroots movement 'No Kings', included over 3,100 events and drew an estimated nine million participants. Notable figures like actor Roberto De Niro joined the rallies, highlighting the deep political divide in the country.
