A proposed UFC 'Fight Night' event at the White House is facing a legal challenge after a federal lawsuit was filed seeking to block the plan. The event, which is part of the celebrations marking America's 250th anniversary and coincides with President Donald Trump's 80th birthday, has drawn scrutiny from critics who argue that hosting a professional mixed martial arts card on government property raises legal and ethical concerns. According to CBS News, the lawsuit, filed by the Public Integrity Project on behalf of a political activist and a US Air Force veteran, labels the proposed June 14 event as 'deeply corrupt' and contends that it is intended to financially benefit President Trump and his associates.The legal challenge further alleges that the Trump administration's authorization of the event on national parkland violates federal law. It also claims that construction plans for the venue - including a large arch on the White House South Lawn - were approved without congressional authorization and proceeded without the environmental reviews typically required for such projects. The lawsuit is seeking a preliminary injunction that would halt the planned June 14 fight card, stop any additional construction related to the South Lawn venue, and block the pre-fight press conference scheduled to take place at the Lincoln Memorial on June 12."The president is giving UFC chief executive Dana White and his company what none have enjoyed before: unfettered access to the White House and Lincoln Memorial to stage a private, for-profit sports event, with all the promotional and branding opportunities that accompany such access," the lawsuit stated as quoted by the outlet.The UFC has maintained that the event is intended to be part of the nationwide celebrations commemorating America's 250th anniversary. However, the lawsuit points out that the proposed fight card is scheduled for June 14 - President Donald Trump's 80th birthday - nearly three weeks before the official Independence Day festivities on July 4.You Might Also Like:— WhiteHouse (@WhiteHouse) "The event is neither 'for the celebration of the 250th anniversary of American Independence' nor, crucially, being 'planned, organized, and executed' by the federal government."Rather, UFC Freedom 250 is being held for the financial benefit of the UFC, Paramount, and their advertisers, and to celebrate the 80th anniversary of Donald Trump's birth," the lawsuit further stated. — UFConParamount (@UFConParamount) The festivities are scheduled to begin on June 12 with an open-to-the-public press conference at the Lincoln Memorial.
