The Trump administration is asking a federal court to let UFC Freedom 250 go ahead on the White House lawn this weekend, arguing that a lawsuit trying to stop the event arrived far too late in the fight card to change the outcome.

Two Virginia residents sued the National Park Service and the Department of the Interior earlier this week, seeking an emergency injunction to block the mixed martial arts event. In their filing, they described the planned White House UFC show as “deeply corrupt” and asked a judge to halt it before the first bout.

Why the administration says the lawsuit is too late

In its response, the administration is leaning heavily on timing. The government says the event has been in development for roughly a year, while the plaintiffs waited until the final days before the scheduled weekend event to take legal action.
