Heatwave and Political Divide Mark July 4th Celebrations

The 250th anniversary of American independence arrived with a heat wave bearing down on millions and a political climate that added tension to the festivities. President Donald Trump spoke on the National Mall before a large fireworks display, while Vice President JD Vance said small voices would focus on America's imperfections. New York City Mayor Zohran Mamdani, a Democrat, appeared to reference Trump in a speech about enduring authoritarian regimes.

Extreme heat forced cancellations and adjustments. Washington's main parade was canceled, though a smaller one rolled through Capitol Hill. Philadelphia held early fireworks near Independence Hall. The heat index in the District of Columbia approached 115 degrees Fahrenheit, according to the National Weather Service. Organizers on the National Mall said they were monitoring conditions.

The heat wave stretched from the Southeast to New England, with triple-digit temperatures in many areas. Officials warned of heat-related illnesses. In New York, tall ships paraded past the Statue of Liberty, and a stealth bomber flew overhead. The Nathan's Famous hot dog contest went ahead on Coney Island, with Joey Chestnut winning for the 18th time, eating 66 hot dogs in 10 minutes. Both champions said the heat made it harder.
