UFC Octagon Takes Over White House South Lawn for Trump's 80th Birthday

It looks from afar more UFO than UFC.

Maybe it's the kind of contraption that has carried space aliens to the White House to force a meeting with America's leader.

But come closer and you'll see the contours of the eight-sided cage, 30 feet (9 meters) in diameter and shaped, with careful precision, like the MMA league's signature Octagon. That is, a STOP! sign flipped on its edge, with wire-mesh sides and padded corners fitted with different sponsors' logos: Morgan & Morgan, Bud Light, Dodge Ram, Corona Extra and Polymarket, which identifies itself as the world’s largest prediction market.

Overhead looms The Claw, a four-sided mass that arcs more than 90 feet (27 meters) into the air and features lights, speakers, thick snakes of wiring and four large screens so fans not seated right next to the Octagon can follow the cage fighting below.

Think more the four-sided, metal grabby thing that tries to grasp stuffed animals at a video arcade rather than what house cats have — hence the extraterrestrial vibes.

And surrounding all that are risers filled with gray folding chairs forming a temporary arena expected to seat 4,000-plus people for the seven UFC fights being staged on Sunday to celebrate the 80th birthday of President Donald Trump and the 250th anniversary of the Declaration of Independence’s signing.

For non-UFC fans, all of this might be disorienting under any circumstances. But the temporary arena is covering nearly the entirety of the White House's South Lawn, where Marine One usually lands to ferry the president to out-of-town trips and gobs of kids scramble in the grass during the Easter Egg Roll every spring.

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 and is contesting a lawsuit meant to block the event.

The White House says the UFC is covering the costs, though the filing states that seven agencies — including the Department of Homeland Security and the Federal Aviation Administration — have “allocated significant resources and manpower.”

Fighters, their entourages and assorted support staffers are expected to take over the driveway and part of the West Wing when they're not fighting. But they'll enter the arena via curtained-off walkways with access to the Octagon.

They, as well as ordinary attendees of Sunday's spectacle, will have picturesque views of the White House's Executive Residence and its storied Truman Balcony on one side and the Washington Monument towering in the distance on the other. All of it will be accentuated by swirling spotlights, and perhaps even sweat and blood pouring off the fighters pummeling each other.

A packed pre-event schedule includes a press conference at the Lincoln Memorial with UFC chief Dana White and the fighters on Friday night.

There's also a ceremonial weigh-in for combatants on Saturday at the Ellipse, a park near the White House where organizers expect 120,000-plus visitors to watch Sunday night's proceedings on large screens after winning free tickets in a lottery.

Stunt athlete Travis Pastrana is also set to do a potentially death-defying backflip on a dirt bike on the White House lawn as part of the preshow extravaganza.

Trump has called the Octagon and its Claw “quite attractive to a lot of people.” He's even suggested that maybe the temporary structure could become permanent, like the Eiffel Tower, which he notes was originally built as part of the 1889 World's Fair but then was never taken back down.

Only the president knows how serious that suggestion really is.

Work on the arena began May 20 and has continued for weeks. During a walk-through for reporters on Thursday, construction noises — particularly sanding and hammering — could be heard. Giant cranes were carrying materials around overhead, though that was for the $400 million ballroom that Trump is building nearby, not the UFC fight.

The remaining grassy lawn around the arena, on the other sides of the White House, has been fitted with supplemental spotlights. But the grass that normally grows between the White House and the start of the risers for the arena is now gone, with nothing but dusty dirt that will need to be resodded when this is all over — unless the president really does decide to leave the arena up permanently.

There's also a large Freedom 250 logo standing between the White House and the arena. Nearby, crews removed the tables and yellow patio umbrellas from Trump’s refurbished Rose Garden and were power-washing that space, as well as the colonnade to the Oval Office, in preparation for the fights.

Sunday's event starts at 8 p.m. ET. As darkness falls, crews will illuminate The Claw in red, white and blue, and the mass of lights will offer projections that make it seem as though the entire structure has been enveloped in a twirling stars and stripes pattern.

The weather forecast calls for hot and muggy conditions with thunderstorms possible. The underside of The Claw's tower features an overhead cover that should keep the fighters reasonably dry should it rain — and Trump is also likely to watch from a protected, covered area.

But everyone else would almost certainly get wet.

White has vowed that even heavy lightning — when The Claw might make a conspicuous target for bolts — wouldn't stop the show.

“I don’t care if it snows,” White said.
