Ella Irwin, Twitter’s head of trust and safety and one of Elon Musk’s top lieutenants, is no longer in Twitter’s internal Slack, according to a source familiar and a screenshot of her deactivated account viewed by Fortune. Irwin declined Fortune‘s request for comment but confirmed her resignation. Reuters also confirmed Irwin resigned from the company, but it is not yet clear why.
A former Amazon director who joined in June 2022, a few months before Musk acquired Twitter in November, Irwin quickly earned the new Twitter owner’s trust and became one of his top executives at the company, overseeing content moderation, after the high-profile departure of the company’s former head of trust and safety, Yoel Roth.
While it’s not yet clear why Irwin has left Twitter, sources at Twitter have speculated about whether her departure might be connected to Musk’s recent criticism of the company’s decision to moderate content from conservative news site the Daily Wire.
