A reunion of the world’s richest man and its most powerful may not be imminent, but at least one of them has expressed his regrets as their relationship lies in ruins.

Elon Musk said on X in the early hours Wednesday that he “regrets” some of the barbs he posted as he and President Donald Trump traded insults on social media, saying “they went too far.”

Musk didn’t elaborate in his 3 a.m. ET message on which posts from last week he regretted, and he didn’t explain what caused his sudden change of heart.
