Donald Trump Jr. sparked controversy after posting a birthday tribute for his daughter Kai, who turned 19 on May 12. The Instagram post featured a mix of childhood photos and several bikini images of Kai, which drew criticism from some users who found the choice inappropriate. While Trump Jr. praised his daughter, calling her his 'absolute favorite 19-year-old child,' many commenters questioned the appropriateness of the bikini photos, noting that Kai does not typically share such content on her own social media. Bettina Anderson, Trump Jr.'s fiancée, remarked on the post, expressing disbelief that Kai is already in college. The birthday celebration was a modest affair held at home, where family and friends gathered for a warm dinner. The catered menu included a variety of dishes, showcasing a family-oriented approach to the celebration. Despite the mixed reactions to the social media post, the family appeared to enjoy the occasion together.
