U.S. President Donald Trump marked his 80th birthday on Sunday (June 15, 2026) by hailing an initial agreement to end the war in Iran and staging a once unfathomable cage-fighting show on the storied South Lawn of the White House.Mr. Trump had been touting the emerging deal for weeks, and last-minute strikes in the conflict had threatened to overshadow the ostentatious UFC mixed martial arts extravaganza — where combatants sealed inside a wire-mesh octagon try to punch, kick, chop and pummel each other into submission.West Asia LIVE - June 15, 2026Hours ahead of the fight starting, however, the President said an agreement to end the conflict “is now complete." He declared that the U.S. will end its blockade of Iran, and that Strait of Hormuz would reopen, potentially easing high oil prices and skittish global markets. But the crucial details are still to be negotiated.Word of the deal was a pre-fight present for Mr. Trump but his focus quickly shifted to UFC. Top administration officials and Republican leaders attended, including FBI Director Kash Patel and House Speaker Mike Johnson. Polish President Karol Nawrocki was spotted heading into the White House for it, too.Mr. Trump and UFC chief Dana White walked together from the Oval Office to the Blue Room Balcony to survey the Octagon and stood for the National Anthem as fighter jets thundered overhead. The crowd chanted “USA! USA!”More than 4,000 spectators were invited to a temporary arena under “ The Claw,” a spaceship-like metal arch fitted with lighting, sound equipment and large screens. Thousands more watched on big screens from the nearby Ellipse.
