Donald Trump’s youngest supporter? Elon Musk’s four-year-old X Æ A-12, apparently. The Tesla founder’s son, whose name is pronounced “ex-ash-ay-12” and who goes by “X” for short, has become a regular on the Trump/Musk circuit of late: carried on his dad’s shoulders during excursions to Capitol Hill to discuss Trump’s government efficiency initiative, DOGE; joining them both at Mar-a-Lago to celebrate New Year’s Eve, if way past the child’s bedtime.
