Ultimate Fighting Championship (UFC) President Dana White has a long and contentious history with fossilized fight promoter Bob Arum, as mixed martial arts (MMA) and boxing continue to battle for the top spot in combat sports.

This time, or at least for a few days, both disciplines will take center stage as UFC lightweight champion Conor McGregor boxes Floyd Mayweather Jr. on Aug. 26 inside T-Mobile Arena in Las Vegas, Nevada.

While a lot of folks are convinced McGregor has a legitimate shot at handing Mayweather the first loss of his professional career, Arum isn’t one of them, and was unfazed by White’s comments that he was too senile to know any better.

Which is the sort of remark he would expect from a Trump supporter (via LA Times):

“Dana can say whatever he wants, but he hurts his argument by resorting to these comments. It has nothing to do with senility. And it hurts the position he’s trying to take. But what do you expect? You didn’t see me at the Republican National Convention endorsing [President] Trump. That speaks volumes of somebody. I completely stick by my guns. It’s nothing personal or argumentative, but to have somebody fight the top fighter of our era with someone who hasn’t had one professional boxing match — they’re out of their mind.”

Trump gave UFC a place to operate in the dark days of MMA, back when cage fighting was considered a blood sport, and thus has White’s loyalty for the rest of his presidential term, however long that lasts.

Which explains this video.

White was instrumental in bringing “The Money Fight” together, which airs exclusively on Showtime pay-per-view (PPV) this weekend in “Sin City.” Not surprisingly, millions of dollars are expected to be earned by all parties.

Which doesn’t include Arum.
