Dana White says it was a "massive f*** up" by the UFC for NOT showing former President Donald Trump during the Conor McGregor fight card.
The UFC prez tells TMZ Sports the flub was a mix of his production team dropping the ball, a technical issue, and the unpredictability of live television.
The way Dana explains it ... there was a plan in place to show Trump sitting near the Octagon. Cameras were supposed to pan from some big-name celebrities to the former Prez .
