According to UFC President Dana White, just about everyone has been calling him for tickets - hoping to be ringside for next month's fight between five division world champion Floyd Mayweather Jr. and UFC superstar Conor McGregor , which takes place on August 26 in Las Vegas.

But is White going to reserve a ticket for his close friend, United States President Donald Trump? (The President is also good friends with Mayweather)

"Funny you say that, but they called me yesterday and I don't think they'll come, but they'll be watching," White said to TMZ.

Asked if Trump wanted to come, White said - "100 percent [he wants to come, but] he feels like he'll ruin the event if he shows up. Secret Service is gonna have to go through the place, they'll have to shut down streets and create crazy traffic."

On Tuesday, the two boxers went face to face at a Los Angeles media conference in first of a four-day international tour promoting the bout.

The contrasts between the two was immediately apparent as McGregor, wearing a navy pinstriped suit and tie, danced around the stage smiling while Mayweather, wearing a track suit with American flag details, looked on stonefaced.

As is expected in the bout, McGregor was the aggressor, wasting no time bringing up reports that Mayweather earlier this month asked the IRS for more time to pay his 2015 tax bill.

“He’s in a track suit,” McGregor told the crowd of more than 11,000 people, who largely cheered the Irishman and booed the American. “He can’t even afford a suit anymore.”

Later when Mayweather, whose nickname is “Money” and who frequently uses cash as a prop, pulled out a $100 million check on stage, McGregor told him to “give it to the taxman”.

When asked about the tax issue, Mayweather said his attorneys were working on it and did not worry him. “I just showed you all a $100 million check that I haven’t even cashed yet, so we ain’t tripping on that,” he told reporters.
