Trump vowed to deliver a "really long" Fourth of July address despite a 107-degree forecast at the America 250 celebration.

For America's 250th birthday, the U.S. government is hosting two major events hosted by rival groups. One got Trump, the other got bigger musical acts.

Trump plans a lengthy speech on July 4 in extreme heat to showcase his resilience.

President Trump said extreme heat in the nation's capital on July 4 won't stop him from giving his big speech ahead of the fireworks celebration.

The president is slated to speak at 9:45 p.m., followed by what has been billed as a record-breaking fireworks show at 10:30 p.m.

With temperatures forecast to reach up to 42 degrees, the US president told an audience he planned to make a long speech, “just to show that I can do anything”.
