Squinting in the sun with Elon Musk, Trump stood next to five Tesla vehicles, holding a piece of paper with handwritten notes about their features and costs. Trump said he would purchase a car himself at full price.

Mr. Musk is fundamentally a creature of Silicon Valley, a scene that initiated an entire revolution in power dressing. The young masters of that universe dressed down to show that they were members of a new elite — one that refused to dress like the grown-ups they were about to topple. It was the defeat of the suit by the T-shirt.

Unelected White House advisor and president Donald Trum's closest buddy Elon Musk isn't too happy about having abandoned his businesses. The mercurial CEO has seemingly spent the vast majority of his time ransacking the federal government and excising what he claims to be "waste" and "fraud" with the help of his so-called Department of Government Efficiency.
