Watch: UFC Heavyweight Champion Jon Jones Celebrates Win With Donald Trump's Trademark 'YMCA' Dance

US President-elect Donald Trump was greeted by chanting fans as he attended the Ultimate Fighting Championship (UFC) heavyweight bout at New York's Madison Square Garden on Saturday. Trump entered the arena shortly before the start of the main card accompanied by UFC chief executive Dana White, who was a prominent backer during his election campaign. Several political allies of Trump were also in attendance for the mixed-martial arts fights, including entrepreneurs Elon Musk and Vivek Ramaswamy, who have been asked by Trump to lead efforts to cut government inefficiency.

Tulsi Gabbard, the former Democratic congresswoman tapped for the role of director of national intelligence, was also in the crowd along with Trump's sons Eric and Don Jr and musician Kid Rock -- a regular at Trump rallies.

After waving to the chanting crowd, Trump warmly greeted UFC broadcast analyst Joe Rogan, the popular podcast host who also endorsed Trump after he appeared as a guest on his show.

The venue's "jumbotron" giant screen above the cage where fighters did battle then showed a video featuring highlights of the election campaign with soundbites from Trump.
