A hulking metal arena is rising on the White House¡¯s South Lawn as U.S. President Donald Trump pursues a spate of construction projects, and is set to host a night of cage fighting to mark the 250th anniversary of U.S. independence.

The mixed martial arts arena ?is being assembled on a stretch of the grounds used for presidents¡¯ Marine One departures ?and annual Easter ?egg rolls and picnics, alongside tennis and basketball courts, a horseshoe pit and ?a garden honoring presidents¡¯ children and grandchildren.
