Federal officials described President Donald Trump's July 4 celebration as "safe" and "well-prepared" just hours after a record heat wave forced organizers to shut down the Great American State Fair and paramedics rushed to aid attendees, several of whom were reportedly hospitalized.In a joint statement Friday, Freedom 250, the U.S. Park Police, the National Park Service, the Secret Service and the Federal Emergency Management Agency said they had coordinated to expand cooling resources, water stations and medical support for the "Salute to America" event."We are proud to welcome the public to a safe, well-prepared, and truly memorable celebration of America's 250th birthday," the statement read.The reassurance arrived alongside a quiet concession. Organizers pushed back public entry to the Washington Monument grounds from 1 p.m. to 5 p.m. "to reduce prolonged exposure to heat," cutting four hours off the window guests can spend on-site.Trump's slot was left untouched, however. The president is still scheduled to deliver remarks at 9:45 p.m., followed by a 10:30 p.m. fireworks display his task force has billed as the largest in history.The statement capped a troubled stretch for the 16-day event. The fair was forced to close for hours Friday as the capital baked under an extreme heat warning, with the heat index projected as high as 113 degrees. One attendee earlier dunked herself in a baptismal pool to escape the heat, and reporters described a largely deserted fairground throughout the week.Washington was forecast to be hotter than 99 percent of the planet on Friday, according to a Washington Post meteorologist.
