A federal judge on Friday refused to block a scheduled UFC event at the White House.

U.S. District Judge Amit Mehta denied a request for a temporary restraining order and preliminary injunction that sought to halt UFC Freedom 250, an event planned for the South Lawn on Sunday.

Mehta ruled the plaintiffs had not demonstrated they would suffer irreparable harm. The judge noted organizers have spent nearly a year planning the event and that UFC and affiliated organizations have invested more than $60 million in preparations.
