Trump is a longtime UFC enthusiast and frequent attendee of major fights. He made promoting hypermasculine tones a signature of his latest, successful campaign for the White House — as he looked to further widen the gap among male voters between himself and his Democratic opponent, Vice President Kamala Harris.

Trump was greeted by thunderous applause as he arrived at the venue flanked by a beaming Dana White.

Two of Trump's key cabinet picks, Robert F Kennedy Jr and Tulsi Gabbard, plus Vivek Ramaswamy, who will lead Trump's cost-cutting “Department of Government Efficiency” with Musk, were also in the crowd.
