Donald Trump Jr.’s wedding was noticeably missing one of his four siblings

Donald Trump Jr got hitched to Bettina Anderson in the Bahamas at the weekend, but not all of his family was there for the big day.

While Ivanka, Eric and Tiffany all attended, it was noted that their half-sibling Barron was nowhere to be seen, and Donald and Melania Trump were also missing from the special occasion.

According to People, the wedding was a surprise secret limited only to very few guests, an the couple are reportedly hoping to have another wedding celebration at the White House with POTUS and the Firrst Lady there.

Don Jr, 48, and Anderson, 39, wanted to 'keep the celebration private and intimate', sources told the outlet.

“July 4 belongs to America, and early fall is not a good time to plan a wedding in South Florida or on the islands due to questionable bad weather, so they decided to do it now in a place they both love," said the source.

This was actually their second wedding, as People has seen a marriage license for a ceremony held in Florida on Thursday, May 21.

They married at Anderson's twin sister's home in West Palm Beach, while her husband officiated.

As for Donald Trump's absence, he tweeted that he could not attend due to ;circumstances pertaining to Government, and my love for the United States of America.'

He wrote on Truth Social: "While I very much wanted to be with my son, Don Jr., and the newest member of the Trump Family, his soon to be wife, Bettina, circumstances pertaining to Government, and my love for the United States of America, do not allow me to do so."

"I feel it is important for me to remain in Washington, D.C., at the White House during this important period of time."

As for why his brother Barron missed it, a source told Rob Schuter that there is distance between the half-siblings: “Barron grew up in a completely different world from Don Jr., Eric, Ivanka, and Tiffany. There’s emotional distance there, and everyone in the family knows it.”

According to Yahoo, a source claimed "Melania did not want to spend a full weekend with Donald’s adult children from previous marriages. That tension has existed for years, even if nobody says it publicly."

The venue, a sun-soaked beach at Norman's Cay in the Exumas is reportedly a favourite place of Anderson.

It has a private airstrip with its own customs clearance, and it can only be accessed by chartered plane or boat.

The happy couple shared pictures on social media to commemorate the day, featuring their hands and rings,

"Forever yours, forever mine," she wrote, adding: "The whole point is to marry your best friend."
