Sam Altman sues sister for defamation over sex abuse claims

OpenAI CEO Sam Altman has filed a defamation lawsuit against his sister Ann after she accused him of sexually abusing her for almost a decade. Ann sued Sam in January, alleging he abused her during their childhood in Missouri. In a court filing, Altman said Ann's lawsuit aims to pressurise him to "accede to her demands for unrestricted financial support".
