Musk's son 'Lil X' steals spotlight in the Oval Office

The billionaire has brought his four-year-old to numerous Washington events.

"This is X, and he's a great guy -- high IQ," Trump said at the top of his remarks, chuckling and calling the four-year-old a "high-IQ individual."

While defending his Department of Government Efficiency (DOGE) efforts, Musk repeatedly got distracted, including after he hoisted his son to his shoulders and "X" played with his father's ears.

"Sorry for this," Musk said. "Otherwise, I might enjoy this, but as he's sticking his fingers in my ears ..." he added with a laugh.

The boy, whose full name is X Æ A-Xii, made faces and mirrored his father's gestures while Musk spoke.

The White House shared a video of the three in the Oval Office, highlighting "Little X" sporting a brown coat and a "cool chain," as described by his father.

At one point, "Lil X" leaned against the historic Resolute Desk, similar to how a young John F. Kennedy Jr. was seen in a famous 1962 photo peering out -- from under the very same desk.
