A UFC fight card is scheduled to take place on the White House South Lawn. The mixed martial arts show is timed for President Donald Trump's 80th birthday and is part of the celebration of the nation's 250th anniversary.
A federal lawsuit has been filed seeking to halt the upcoming event. The legal challenge claims that the U.S. president did not seek proper approval for the fighting event to be held on his 80th birthday.
Despite the legal challenge, preparations are currently underway, with crews erecting an octagon-shaped cage on the South Lawn.
