'I Can Do Anything': Trump Promises Long Speech as DC Braces for Its Hottest July 4 Ever

President Trump vowed this week that he will deliver a long speech on the National Mall for the nation's 250th birthday celebration — even as forecasters warn Washington, D.C., could see temperatures approaching 107 degrees Fahrenheit on Saturday.

"On July 4th, it's going to be approximately 107 degrees out, and I'm going to go, and I'm going to make a really long speech just to show that I can do anything," Trump said during his appearance at the opening ceremony for the Theodore Roosevelt Presidential Library in Medora, North Dakota.

Washington's all-time record for the hottest temperature on the Fourth of July was set in 1919, when the high reached 100 degrees. Saturday's forecast would shatter it.

The Scale of the Celebration

The event, organized under the America 250 banner marking the country's 250th anniversary, is one of the largest outdoor gatherings Washington has seen in years. The program spans the National Mall between 14th and 17th Street and includes a FIFA World Cup watch area, the Great American State Fair, and military flyovers beginning at 1:15 p.m. that run on the hour until sunset. Opening programming begins at 5 p.m., with the formal Freedom 250 Salute to America starting at 7 p.m.
