Elon Musk’s four-year-old son blended in perfectly in the Oval Office with all the other bogeymen | Catherine Bennett

Regardless of anxiety by most parents about over-sharing, the president's aide brought one of his children to the White House

If the reversal of declining birthrates is genuinely a preoccupation of Elon Musk's, recent reviews suggest that the exhibition of his four-year-old son, X", may not be the most effective fertility stimulus.

I say idly". Donald Trump, in attendance, introduced X as a high IQ individual".
