Former President Donald Trump knows how to set a crowd on fire, and that's exactly what happened over the weekend at UFC 290.

Making a surprise appearance at the big fight, Trump walked it to thunderous applause, accompanies by the league’s CEO, Dana White, one of Trump's allies in the sports world.

The high-profile event occurred Saturday night at the T-Mobile Arena in Las Vegas.

The former president continues to make headway in his quest for the Republican nomination and ultimately the presidency in 2024.

In stark contrast to whenever President Joe Biden shows up at a public event, virtually the entire crowd at the the T-Mobile arena on Saturday night went absolutely bonkers when the former president walked to his seats with White.

The former president's visit was unannounced, presumably for security reasons, making his appearance all the more exciting for the amped-up audience.

Fox News noted:

The 45th president of the United States was his usual social self, interacting with fans by shaking hands and talking for a few moments as he made his way toward the octagon.

The former president also made headlines earlier this year with his surprise attendance at UFC 287.

Trump is known to be a fan of both boxing and mixed martial arts (MMA), and has made appearances at countless previous high-profile fight nights around the country.

"LIVE NOW: President Trump visited UFC 290 where the entire arena went crazy when he entered. Meanwhile, Joe Biden went to the beach, where not even a single person seemed to notice or want to meet him. I don't need a poll to tell me who is more popular!" former New York City Mayor Rudy Giuliani tweeted.
