But despite showing up for his father Donald Trump, a lip reader did notice a moment of family rancour during the almost two-hour divisive speech, with Barron apparently giving Ivanka a rude response to a cryptic question.
Lip reader Jeremy Freeman told the Mirror that he noticed the siblings having a quiet conversation while President Trump wheeled through a seismic and controversial year in America’s domestic and international politics.
Freeman said that he detected Ivanka, 44, asking her younger sibling ‘What are you doing on…?’, though he did not catch the initial context or subject matter of her probing question.
But in a reply that is no doubt familiar to big sisters around the world, Freeman says that Barron gave a particularly surly retort that began with the New York University student saying ‘I’m not sure…’. Then he added four rude words to his response.
“I couldn’t be a***d,” Barron apparently told Ivanka.
Freeman was not the only one to notice that Barron and Ivanka had something of a dynamic during the State of the Union, which at an hour and 47 minutes in length was the longest in American history.
Body language expert Judi James told the Daily Mail that the rare sighting of all five Trump children in one place showed a new dynamic among the siblings, with their posture revealing that Barron and Ivanka could become a new force in the family.
She said: “Barron and Ivanka seemed to have formed a new sibling power couple, sitting side by side, with Barron looking watchful and serious while Ivanka chatted to him until they were engaged together in some ongoing conversation.”
Meanwhile, Charlie Kirk’s widow, Erika, also received the lipreading treatment, as she was seen mouthing a three-word phrase when President Trump paid tribute to her late husband, who died on September 10, 2025.
