President Donald Trump celebrated his 80th birthday and the United States 250th birthday with a UFC event on the White House South Lawn. The evening featured the first professional sporting event held at a presidential residence and led to a lightweight championship bout between American fighter Justin Gaethje and Russian‑Iraqi fighter Ilia Topuria. Gaethje emerged victorious, and the fight was broadcast exclusively on Paramount+, a platform owned by a Trump ally.

More than 4,300 people attended the invite‑only attendance on the lawn while an estimated 85,000 additional fans watched screens set up in a nearby fan zone. The event included a massive 92‑foot metal “Claw” structure that resembled an Eiffel Tower and a temporary UFC octagon. The fighters were escorted onto the stage by Medal‑of‑Honor recipients and first‑responders, and several high‑ranking officials, including FBI Director Kash Patel and former President Trump supporters, were present.

The evening faced a one‑hour weather delay as thunderstorms threatened the grounds, with temperatures reaching 91 degrees Fahrenheit. Despite the delay, the fighters returned to complete a total of 14 matches on the evening, culminating in the highlighted main bout.

Before the fight, a lawsuit filed by a Vietnam veteran and civic activist sought to halt the event, citing corruption and lack of official approvals. A judge denied an emergency injunction, allowing the fight to proceed. The lawsuit was dismissed by the White House as frivolous.

Polling revealed that only 16 percent of Americans believed it was appropriate to host a UFC event at the White House, while 46 percent deemed it inappropriate. Republicans were less supportive, with only about one‑third approving the plan. The event coincided with other 250th anniversary celebrations including an IndyCar race around the National Mall.
