President Donald Trump's UFC fight on the White House's South Lawn requires a monumental effort from more than seven federal agencies, hundreds of staff working onsite daily and about $60 million. The event is part of the 250th anniversary of America's founding and is scheduled for the weekend with seven mixed martial arts matches on Sunday. But a lawsuit filed by two Virginia residents seeks to stop it. The agency filed a rebuff of the request in court, noting that the $60 million is coming from the UFC and groups affiliated with it. The document does not specify the extent of government resources spent on the project, but said that seven agencies, including Homeland Security and the Federal Aviation Administration, have “allocated significant resources and manpower.”
