President Donald Trump is scheduled to deliver a lengthy speech on the National Mall Saturday evening in Washington, D.C., marking the United States' 250th anniversary. The celebration includes military flyovers, events at the Great American State Fair, and a large fireworks display throughout the day. However, record-breaking heat threatens to disrupt the planned festivities.

First Lady Melania Trump is also involved in the day's events. Despite the weather concerns, the celebrations continue as the nation commemorates this milestone.
