President Donald Trump and “First Buddy” Elon Musk’s viral joint press conference in the Oval Office on Tuesday could not have gone better—at least according to one body language expert. As Musk talked robotically at length about uncovering alleged government “waste”—and his four-year-old son X Æ A-Xii squirmed and at one point shushed Trump—political pundits declared Trump had been humiliated.

Right in front of Mr Musk was his four-year-old son X Æ A-Xii, also named X. While the press briefing at the White House usually has a serious tone, filled with important discussions and major decisions, this one soon turned into a light-hearted one, with the child stealing the show.
