WASHINGTON — President Donald Trump turned 80 on Sunday and was set to celebrate with one of the more surreal spectacles both in sports and even in the nation’s capital: cage fighting on the White House lawn.

Against the backdrop of a 3-month-old war with Iran that’s been broadly unpopular with Americans and has rattled global oil markets and with inflation spiked to the highest level since April 2023, the White House — long known as the people’s house and a symbol of American democracy — opened its backyard Sunday night to stage a bruising UFC card on the South Lawn.

More than $60 million and tens of thousands of hours of labor have been poured into building the arena, according to a court filing from the National Park Service, which oversees the South Lawn.

UFC is staging seven fights with all male fighters under the Freedom 250 banner to celebrate Trump’s 80th birthday and the 250th anniversary of the Declaration of Independence’s signing.

It’s the pinnacle of the relationship between UFC CEO Dana White and Trump that has yielded personal, political and financial dividends for both parties in a relationship that goes back 25 years. White’s first card as UFC president came in 2001 at an event held at Trump Taj Mahal.

Trump has attended four UFC cards as sitting president, walking to the cage amid rock music and patriotic chants from fans much like the fighters themselves. White introduced Trump at two Republican National Conventions. White also attended the White House Correspondents’ Association dinner in April that was cut short by a shooting.
