President Donald Trump marked the 250th anniversary of American independence with a speech at Mount Rushmore, emphasizing American exceptionalism but also warning against the threat of communism, which he described as a significant danger to American liberty. His rhetoric echoed the Red Scare of the 1950s, contrasting with the typically unifying speeches of past presidents. Meanwhile, a heatwave affected Independence Day celebrations across the eastern U.S., leading to event cancellations and adjustments. In Washington, festivities continued with concerts and fireworks, despite the oppressive heat. The day also saw Glenn Brooks, pardoned by Trump for his role in the January 6 Capitol attack, expressing gratitude for participating in the celebrations.
