The United States marks its 250th birthday on Saturday, with large public celebrations centered on the National Mall and the anniversary of the 1776 Declaration of Independence. President Donald Trump addresses tens of thousands after storms and severe weather delay his remarks and force evacuations during the approach of thunderstorms. Despite sweltering heat—affecting millions under extreme weather warnings—events continue across multiple cities, including a planned supersized fireworks display, military flyovers, and other performances.

Trump frames the occasion as a celebration of American exceptionalism and calls the United States a “crowning achievement” of human history. He also highlights veterans from the World War II, Korean, and Vietnam eras. In addition, he renews his message that the nation faces a “renewed attack” from domestic “radicals and extremists,” with particular reference to a “resurgence of” communism, echoing remarks he made in earlier days.

The broader anniversary is marked by political divisions. Reports describe disagreements about whether the country lives up to Declaration-era ideals, and show that some Americans participate selectively or express discomfort with the event’s political tone. Other leaders, including Pope Leo XIV and King Charles III, also use the occasion to emphasize aspects of values and inclusion.
