Linda Yaccarino is stepping down as CEO of X after two years leading Elon Musk’s social media company. Yaccarino’s departure comes one day after the company’s Grok chatbot began pushing antisemitic tropes in responses to users. It’s not clear that the events were connected.

Yaccarino led X through a tumultuous period as the social network tried to rebuild its relationship with brands concerned that their ads could show up next to offensive content.
