Linda Yaccarino, whom Elon Musk hired to run X in 2023, grappled with the challenges the company faced after Mr. Musk took over.

The CEO of X, Linda Yaccarino, said on Wednesday she would step down from the role in a surprise move, ending her tenure at the Elon Musk-owned social media platform that has faced several controversies and challenges including a mass exodus of advertisers from the site.

Elon Musk's X has taken the automated account for Grok, its AI chatbot, offline after it spent Tuesday afternoon pushing antisemitic narratives.

We are aware of posts made by Grok and are actively working to remove the inappropriate posts,” Musk's company said.

"I'm incredibly proud of the X team - the historic business turn around," Linda Yaccarino wrote on X.
