A federal lawsuit has been filed by two Virginia residents to prevent a UFC fight scheduled for June 14 on the South Lawn of the White House, coinciding with President Donald Trump's 80th birthday and the celebration of the nation's 250th anniversary. The lawsuit, initiated by the Public Integrity Project, claims that the Trump administration's approval of the event is unlawful, violating National Park Service regulations that prohibit sporting events on federal parklands. The plaintiffs argue that Congress did not consent to the construction of a towering arch overlooking the event space, and that no environmental review was conducted prior to construction. Brendan Ballou, the attorney representing the plaintiffs, described the event as a corrupt use of national monuments for private gain. In response, the White House characterized the lawsuit as an obstructionist and baseless attempt to hinder the event, asserting it is similar to other permitted events held on the South Lawn and surrounding areas. The UFC has plans for a 5,000-seat arena and will distribute up to 85,000 free tickets for spectators at both the South Lawn and the nearby Ellipse, where large screens will broadcast the fights.
