Kash Patel was spotted at UFC 320 on Saturday night in Las Vegas as he took a break from his duties as FBI director.
Patel, 45, was seen sitting near the octagon as he raised his fist to the camera.
He donned a black t-shirt with an American flag on the corner as he took in the action at T-Mobile Arena.
The main event on the night was the light heavyweight clash between Magomed Ankalaev and Alex Pereira, while Merab Dvalishvili and Cory Sandhagen also fought in a co-main bantamweight fight.
Earlier in the night Jiri Prochazka knocked out Khalil Rountree in the third round of their light heavyweight fight.
Patel's appearance at the fight night came after a report alleged that he fired an FBI agent for having a gay pride flag on their desk.

The outing comes after it was reported that the FBI boss fired a trainee for displaying a gay pride flag while serving under Joe Biden
Patel's boss, President Donald Trump, is a friend of UFC founder Dana White
The trainee is said to have displayed the emblem while serving in a field office in California last year during President Joe Biden's administration.
According to a letter obtained by MSNBC, Patel later sent a termination letter to the trainee dated October 1, citing Donald Trump's constitutional power to fire bureaucrats serving in the executive branch.
'After reviewing the facts and circumstances and considering your probationary status, I have determined that you exercised poor judgment with an inappropriate display of political signage in your work area during your previous assignment in the Los Angeles Field Office,' the letter read.
'You are being summarily dismissed from your position as a New Agent Trainee at the FBI Academy in Quantico, Virginia, and removed from the federal service.'
The FBI did not respond to a previous request for comment from the Daily Mail.
Patel's boss, Trump, has of course displayed an enthusiasm for UFC, as he's been seen taking in the company's product in person at least two times during his second term.
And Trump and the White House are even planning to host a UFC card on the White House lawn next summer.
Trump met with UFC founder and MAGA supporter Dana White last month, after which White told his 10.7 million Instagram followers: 'The White House fight is on. We got it done today.'

While it was previously believed that the fight was set for July 4, sources involved in the planning of the event told the Wall Street Journal that the event will take place some time in June 2026.
Nonetheless, stunning AI-generated renderings of what the event could look like were first released to Fox late last month, as fans were given a preview of the proceedings.
The images show the White House draped in red, white and blue lights, with thousands of fans situated outside and the traditional 3D UFC graphics displaced for broadcast.
Another snap shows the weigh-ins and press conferences, with a stage set outside the picturesque Lincoln Memorial at night.
UFC reportedly plans to have a large presence in D.C. ahead of the event, with multiple days of festivities on the National Mall.
This could include autograph sessions with UFC stars and even punching-bag setups for visitors.
Conor McGregor has declared he'll be fighting Michael Chandler at the event, for which there is clearly great enthusiasm.
'This will be one of the greatest and most historic sports events in history, and President Trump hosting it at the White House is a testament to his vision to celebrate America's monumental 250th anniversary,' Trump spokesman Steven Cheung said.
