For years, Donald Trump’s critics have accused him of behaving like a crooked used-car salesman. Yesterday afternoon, he did it for real on the White House South Lawn.

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. Then Trump and Musk got into one of the cars. Musk explained that the electric vehicle was “like a golf cart that goes really fast.” Trump offered his own praise to the camera: “Wow. That’s beautiful. This is a different panel than I’ve—everything’s computer!”

This was a stilted, corrupt attempt to juice a friend’s stock, and certainly beneath the office of the presidency. But you ought not to overlook just how embarrassing the spectacle was for Musk.
