Who is Kai Trump? Donald Trump’s eldest grandchild shares social media posts from D.C. ahead of inauguration

Donald Trump is often referred to as “President Trump” or “Mr. President,” and has formerly been known as “Commander in Chief,” “POTUS” and “45,” as he was the 45th President of the United States. 

Following a presidential election victory in 2024, Trump will take office again as the 47th president following Inauguration Day on Monday, January 20, 2025. He has also enjoyed several other prominent titles.

However, before Trump was the leader of the free world, he was lovingly known as “dad” to five children, including Donald Jr., Ivanka, Eric, Tiffany and Barron, and “grandpa” to 10 grandchildren, beginning with the eldest, Kai.

Kai, 17, took to social media this weekend to post herself preparing for the highly anticipated inaugural swearing in ceremony.

“God Bless America,” she wrote on an Instagram video of herself watching fireworks in Washington, D.C.

She also shared a video of herself and two friends on Saturday dancing to a Justin Timberlake song with the caption, “On the way to DC.”

Kai started college in the fall of 2024 at University of Miami where she committed to playing on the golf team.

The eldest grandchild of Trump was seemingly ready to be cast into America’s political spotlight after she spoke at the 2024 Republican National Convention on Day 3 of the event in Milwaukee.

“He calls me during the middle of the school day to ask how my golf game is going and tells me all about his, but then I have to remind him that I’m in school, and I’ll have to call him back later,” Trump’s granddaughter told a raucous crowd in Milwaukee.

“On Saturday, I was shocked when I heard that he had been shot, and I just wanted to know if he was okay,” Kai said at the time, describing the events following the attempted assassination of the former president.

“A lot of people have put my grandpa through hell, and he’s still standing,” the teenager added.

“Grandpa, you are such an inspiration and I love you,” Trump said. “The media makes my grandpa seem like a different person. But I know him for who he is. He’s very caring and loving. He truly wants the best for this country. And he will fight every single day to make America great again. Thank you very much.”
