Pope Leo XIV’s brother Louis Prevost attended President Donald Trump’s UFC event at the White House June 14 and was introduced to the President ringside by Vice President JD Vance.
Prevost, wearing a short-sleeve button-up shirt featuring an American flag and the letters "USA," was among more than 4,000 spectators at UFC Freedom 250, held on the South Lawn of the White House on Trump's 80th birthday.
The mixed martial arts event was hosted as part of the White House's partnership with UFC President Dana White. Trump watched the fights from cageside along with several administration officials, including Secretary of State Marco Rubio and Defense Secretary Pete Hegseth.
The White House shared a photo showing Louis Prevost and his wife, Deborah Prevost, posing with Vance at the event.

NBC News first reported that Vance introduced the couple to Trump during the fight card.
JD Vance introduced Pope Leo's older brother to Trump tonight at UFC Freedom 250. Although previously clashing with the pope, Trump has called his brother, Louis Prevost, "all MAGA." @ellie_skelly and I spotted the moment on camera --> https://t.co/6DRAlxg09K

Trump has publicly expressed admiration for Prevost. In a Truth Social post earlier this year, Trump described him as "all MAGA" amid public disagreements between the president and Pope Leo over the Iran war.
