A large cage fighting arena is being built on the South Lawn of the White house in preparation for Trumps birthday event.
"We're having a big fight. It's never going to happen again, never happened before," Trump said at an Oval office event earlier this month.
Trump says that 4,500 will be able to watch the UFC fight on the White House Lawn and a further 100,000 people are able to watch for free on screens just outside of the White House.

The cage and stage will be surrounded by temporary seats on the lawn of the White House. There will also be a ringside where a marching band will be positioned on the day.
The event takes place on the US holiday, Flag Day, which just so happens to be Trump's birthday.
This is just one event from the series which is planned to celebrate the Declaration of Independence's signing on July 4, 1776. An IndyCar race and the Great American State Fair have also been planned to mark the occassion.
The event that the US President is planning for his birthday has raised concern, for the total cost of the event and for the location as it is set to take place on the historic White House lawn.
UFC's parent company said earlier this year that the event will cost at least $60 million to stage, however they also said that hoped to recover the costs through sponsorships.
According to a report in RTE, The White House stated that "no taxpayer money is being used" for the event and that the UFC is covering the costs.
In an interview with Time magazine, UFC boss Dana White, denied that the event was political as people online have been outspoken against the event. Podcaster Joe Rogan stated that is would be "weird" to have a fight at the White House in the middle of a war.
"You can make anything political if you want to. This is basically me spending a s**t-load of money to celebrate the 250th birthday of America, with America and the rest of the world," Mr White said.
