Yahoo Sports reports: For most of its 250-year history, the White House South Lawn has been reserved for state dinners, diplomatic ceremonies, Easter egg rolls, turkey pardons and carefully choreographed displays of presidential power. Beneath a giant steel canopy known as the Claw, with military flyovers overhead and thousands of spectators spread across the South Lawn and nearby Ellipse, Donald Trump celebrated his 80th birthday and the forthcoming 250th anniversary of US independence by staging the first professional sporting event in White House history. The spectacle ended shortly after 1am on Monday with one of the bigger upsets in UFC history as Justin Gaethje rallied from several perilous moments to stop the previously unbeaten Ilia Topuria after four brutal rounds and claim the undisputed lightweight championship.
