Eric Trump, the son of US President Donald Trump, named the three fighters who, in his opinion, must perform at the tournament in the White House.
The show, scheduled for next June, will commemorate the 250th anniversary of US independence.
"Jon Jones should fight in the White House. I would love to watch him. I think he can still have a fight, and if there's anywhere he should fight, it's the White House.
I think you'll see McGregor in this card. I know him well, a great guy. There's a lot of talent in the UFC right now. We need to put on a great American show on America's birthday at the White House.
I've grown close with Bo Nickal, this guy was undefeated when he competed in wrestling for the University of Pennsylvania, a true American champion," MMA Mania quotes Trump Jr. as saying.
