MSNBC host Lawrence O’Donnell also said that the little boy’s presence in an Oval Office press conference with Trump Tuesday was ‘a power play’ by the tech billionaire.

The antics of Elon Musk's adorable son in the Oval Office were charming, but the boy's mom was not amused. "He should not be in public like this," Grimes says on social media. The singer was responding to a fan who complimented her son's manners.

Elon Musk brought his son, X Æ A-Xii or “Lil X,” to an Oval Office meeting with President Donald Trump, and was criticized by the boy’s mother, Canadian musician Claire Elise Boucher, known as Grimes.
