The United States marks the 250th anniversary of its Declaration of Independence on Saturday with celebrations overshadowed by a record-breaking heat wave across the East Coast and a deepening political row over President Donald Trump’s dominant role in the events. A parallel commission, Freedom 250, created by Trump last year, has absorbed funding and control from the congressionally mandated America 250, according to a Democratic congressional report. The report, released ahead of the holiday, alleges that the president turned the commemoration into a "focus of corruption and personal enrichment," staffing the new body with campaign operatives and diverting resources.

From Washington, the Trump administration presents the day as a grand patriotic spectacle, with the president scheduled to deliver a lengthy evening address on the National Mall followed by what officials bill as the largest fireworks display in the nation’s history. At a pre-event speech at Mount Rushmore on Friday, Trump described communism as a "mortal threat to American liberty," comparing it to the world wars and the 9/11 attacks. In New York, Democratic Mayor Zohran Mamdani offered a contrasting message, stating that American ideals are "strong enough to endure any authoritarian regime, but only if we reach for them." Polling data released by the Pew Research Center and Gallup show that two-thirds of Americans believe the country’s best days are behind it, and 77 per cent think the Founding Fathers would be disappointed with the current state of the nation.

The extreme heat, with temperatures forecast to reach 42 degrees Celsius in Washington, has forced the cancellation of the capital’s Independence Day parade and the temporary closure of the Great American State Fair. The National Weather Service warned that the heat index could hit 46 degrees Celsius in some eastern cities, posing a deadly risk to those without adequate cooling. Organisers added water stations and medical support, but the conditions have complicated logistics for the mass gathering on the Mall, where security is already heightened with fencing and a heavy police presence.

Viewed from European capitals, the 250th anniversary is unfolding as a display of American division rather than unity. The sidelining of the independent America 250 commission and the Trump administration’s tight control over the narrative have drawn comparisons to campaign rallies, with the midterm elections four months away. The main event on Saturday night, with Trump’s speech and the fireworks, is expected to draw large crowds, but the political fallout from the congressional corruption allegations is likely to continue in the coming weeks as lawmakers return from the holiday recess.
