Donald Trump and his golf-loving granddaughter Kai attend Ryder Cup together

President Donald Trump was joined by his granddaughter — and fellow golf lover — Kai Trump at Friday’s Ryder Cup.

The duo showed up to the Bethpage Black golf course in Farmingdale, N.Y., together to watch the biennial tournament.

The commander-in-chief, 79, dressed formally for the occasion in a suit and golf shoes.

The 18-year-old, for her part, paired black jeans and sneakers with a white sweatshirt from her new collection, featuring her initials in blue and red letters.

She and Donald took in the sporting event from a shielded area.

The family members have been vocal about their shared love of golf over the years, with Kai referencing the sport in her Republican National Convention speech in July 2024.

“He calls me during the middle of the school day to ask how my golf game is going and tells me all about his,” the teen joked at the time.

“But then I have to remind him that I’m in school and I’ll have to call him back later,” she quipped.

In April of the following year, Donald praised his grandchild’s skills in a gushing video.

“I play a lot of golf with Kai and she’s a fantastic golfer,” the politician said in April. “She’s doing really well and she wins a lot of matches.”

The “Apprentice” alum added, “Some day she’ll be able to beat her grandfather, but I’m not sure when that’ll be. It might be a long time.”

Kai, notably, committed to the University of Miami’s golf team in August 2024.

“I would like to thank my Grandpa for giving me access to great courses and tremendous support,” she wrote in her “beyond excited” Instagram announcement last year.

The athlete is set to start next year as she is currently a senior in high school at the Benjamin School in Palm Beach, Fla.

Kai documented the milestone moment for her social media followers last month.

“I cannot believe it’s my last first day of high school,” she captioned celebratory snaps in August. “Senior year here we come.”
