Tesla CEO Elon Musk and President Donald Trump appear to be in the kind of chaotic relationship that social media lives to warn you about. First the two seemed to be enjoying a business alliance-turned-bromance when Musk was invited to become a special government employee in January and spearhead the Department of Government Efficiency (DOGE).

How should a corporate board respond to a CEO publicly insulting and shaming a sitting president? It’s not a question that most need to consider, since few chief executives dare to directly criticize the White House.

Musk attacked Trump directly over his signature spending bill for the first time Thursday, sparking an explosive back-and-forth.
