A federal lawsuit filed by the Public Integrity Project seeks to stop the upcoming UFC fight scheduled for June 14 on the White House South Lawn.The plaintiffs argue that the administration violated park regulations and failed to conduct an environmental review for the construction of a large arena.Critics describe using the Lincoln Memorial for weigh-in events as a desecration of a historic site intended to honor military veterans.The White House dismissed the lawsuit as an obstructionist effort, asserting that the gathering complies with previous protocols for federal land usage.
