Donald Trump has myriad ways to hurt Elon Musk if he wants to

THERE WAS a time, not long ago, when an important skill for journalists was translating the code in which powerful people spoke about each other. Carefully prepared speeches and other public remarks would be dissected for hints about the arguments happening in private. Among Donald Trump’s many achievements is upending this system.

Journalists must now try to guess what is real and what is for show.
