After insisting as recently as 2022 that “for Twitter to deserve public trust, it must  be politically neutral,” Billionaire Elon Musk has changed course and is now leaning hard on his new conservative identity as a booster of President Trump, spending all hours of the day demanding voters support the former president this November. His social media platform X — facing revenue losses and a sharp decline in overall value — is arguably now the greatest megaphone the former president has, thanks in part to Mr. Musk.

The billionaire technology entrepreneur bounded onstage alongside the former president on Saturday night at Butler, Pennsylvania, on the same ground where in July Trump was shot and winged. He donned a black Make America Great Again hat, declaring himself to be part of the movement.
