Thousands chant ’USA’ as former President Donald Trump enters the arena to watch UFC 264.

VIDEOKINGS -- Just before the main event of UFC 264 between Conor McGregor and Dustin Poirier, former President Donald Trump walked into the event to a roar of cheers inside T-Mobile Arena on Saturday night.  Trump came through the fighter tunnel before the welterweight bout between Gilbert Burns and Stephen Thompson. The crowd was on its feet as he was escorted to his seat near the octagon, near where supporter and New England Patriots owner Robert Kraft was seated.
