On Monday, the Politico website published an analysis under the headline “Why has Elon Musk disappeared from the spotlight?” It found a sharp drop in the number of times that Trump posted about Musk on his Truth Social platform, from an average of four times a week in February and March to zero since the start of April.

In addition, White House officials no longer fill their social media feeds with Musk-related content. Reporters seldom ask about him at the White House press briefing. Members of Congress are giving his name a wide berth.

Musk seems to be taking the hint. This week, the Tesla chief executive confirmed that he had reduced his role as the unofficial head of the so-called “department of government efficiency” (Doge) to just two days a week, and will also cut his political spending substantially – the latest public signal that he is shifting his attention back to his business empire amid growing investor concerns.
