The suit was brought by the Public Integrity Project - which is funded in part by ActBlue - on behalf of two Virginia residents and targets the Department of the Interior and National Park Service.

Brendan Ballou, founder and CEO of the Public Integrity Project - and is perhaps most notably a former federal prosecutor who served in the Department of Justice during the Biden administration. He worked in the Antitrust Division as Special Counsel for Private Equity and was detailed for two years to the team prosecuting January 6 Capitol rioters. He resigned from DOJ after President Trump issued pardons for many January 6 defendants in January 2025.

The complaint alleges the event violates federal regulations by staging a private sporting event on federal parkland (generally prohibited by National Park Service rules), constructing a large temporary structure ("the claw") without required congressional approval, and failing to conduct an environmental review under the National Environmental Policy Act (NEPA), ESPN reports.

The plaintiffs argue the event is a private commercial venture benefiting UFC, Dana White, and President Trump (including through sponsorship packages reportedly priced at $1–1.5 million and potential promotional value), rather than a legitimate government-sponsored semiquincentennial celebration. They are seeking an emergency preliminary injunction.

Ballou has described the event as "a profound misuse of our sacred national monuments for private gain" and a "deeply corrupt scheme."

Also Biden folks...
