From ESPN:

At 39, Dana White, the president of Ultimate Fighting Championship is both czar and star of one of the world’s fastest growing sports – mixed martial arts. He is at the epicenter of an enterprise that has moved from spectacle to sport in less than a decade. Mostly, White is outside-the-box, and at times, out of control. Last month, he created a national stir after posting a three-minute, profanity-laced tirade on his website aimed at MMA reporter Loretta Hunt. An E:60 crew had unprecedented access to White over a four-month period – following him to UFC events in Las Vegas and Montreal, and travelling with him to New York and Boston, for an in-depth look at White, arguably the most polarizing leader in sports, who has made enemies and allies at nearly every turn.

The piece is scheduled to air on Tuesday, May 12th at 7PM ET on ESPN.
