Trump shows renderings for UFC White House event: 'Greatest show on earth'

While hosting the fighters, Trump showed pictures of what the event will look like, with the White House smack-dab in the background and 4,000 up-close seats surrounding the octagon.

There will also be a makeshift arch covering the fighters that will be lit up.

"I'm a big sports fan. There are no people tougher in sports than the people behind me. These are the toughest. I know them all," Trump said in the Oval Office.

Trump said the "big fight" will be the "greatest show on earth." He also said upward of 100,000 people will be able to watch the fights in Washington, D.C. with eight large screens near the White House.

"What an unbelievable honor. ... To have a president that's willing to go against an upstream and against the norms is truly special. That's why you got my vote. And it's why we're such a great nation right now compared to where we were," Gaethje said.

Gaethje also credited Trump for UFC's popularity today, saying it would be "10 years behind" if it wasn't for Trump's support in the early '90s while UFC was struggling to be a mainstay due to its violent nature.

Michael Chandler will fight Mauricio Ruffy, and other fighters on the card include Bo Nickal and Sean O'Malley.
