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.

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

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

Linda Yaccarino is stepping down as CEO of X after two years running the company, she announced today. She was appointed its CEO in the year after Elon Musk bought and renamed the company previously known as Twitter — so far, there is no word on who will replace her.
