Twitter faces leadership shakeup as top trust and safety officials resign.

Twitter's head of trust and safety, Ella Irwin, has resigned from her role at the social media platform after serving for roughly seven months. Irwin declined to provide a reason for her decision. She ran the Twitter team that fought disinformation, removed offensive content, and helped maintain Twitter's platform integrity. Her departure comes at a turbulent time for the social media network, which was grappling with the dissemination of a conservative website's purported documentary on transgender people.
