Who is UFC owner Dana White and what is his relationship to Donald Trump?

As US President-elect Donald Trump announced victory late last night after clinching Pennsylvania, the usual suspects appeared on stage beside him.

His wife Melania Trump, daughter Ivanka, sons Eric and Baron Trump and his Vice President pick JD Vance were all on stage alongside him.

While people may be accustomed to seeing the likes of billionaire Elon Musk and Robert F. Kennedy Jr at his recent rallies, it was UFC owner Dana White who made the most impassioned speech last night.

Who is the billionaire behind the mixed martial arts juggernaut, and what is his connection to the next President of the United States?

Here is everything you need to know....

Dana Frederick White Jr is an American businessman and chief executive of the global mixed martial arts organisation known as the Ultimate Fighting Championship (UFC).

In 2001, he struck a deal with brothers Lorenzo and Frank Fertitta to buy UFC from Bob Meyrowitz and have himself installed as the new president of the company.

Since then, he has taken it from a fringe blood sport to a billion-dollar enterprise with events all over the world.

As he was getting things up and running in his new role, he turned to Donald Trump to find venues for his fights.

Both UFC 30 and 31 took place at what was then known as Trump Taj Mahal in Atlantic City, New Jersey. That was the beginning of a long-term friendship between the two businessmen which still stands today.

As Trump said in his speech last night: "So Dana started UFC and came to me because nobody wanted to give him arenas for it because it is a rough sport.

"I helped him out a little bit and I said 'this is the roughest sport I have seen' but I began to like it, and he loves it."
