The Great American State Fair, promoted as a centerpiece of the U.S. 250th anniversary celebrations and linked to President Donald Trump, draws low attendance as a heat wave affects Washington, D.C. Multiple reports describe visitors and revelers arriving in thin numbers even before temperatures rose, with the event facing additional disruptions including technical problems and weather delays. Some outlets report that officials deleted aerial photos showing small crowds after Trump was reportedly upset about the turnout. Others note that Trump claimed attendance numbers that do not match images of the fairgrounds.

The heat also contributes to safety and access changes for related events. U.S. Capitol Police restrict rehearsal access for “A Capitol Fourth Concert,” citing guidance after consulting with the Capitol’s attending physician, while warning that public access is not allowed for the rehearsal. At the fair itself, at least one rodeo demonstration is canceled, and some attendees report booths without air conditioning, with at least one person describing overheating and seeking relief at a cooling spot. For July 4, additional concerns are raised about an outdoor rally on the National Mall scheduled for late evening, with forecasts near or above 100 degrees and no allowance for coolers.
