White, 57, is president and chief executive of the UFC, the largest and most successful organization in mixed martial arts. When Trump won reelection in 2024, White appeared alongside the Republican for his victory speech.
On his 80th birthday in June, the UFC held a bloody cage match on the White House South Lawn.
The card put fighters in a cage on the grounds of the executive mansion, a setting more often used for ceremonies than for combat sports.
The White House amplified the announcement by publishing a screenshot of the president's post on one of its official accounts.
The promotion's violent cage fights are broadcast across the globe, well beyond any single arena night.
