OpenAI chief Sam Altman denies sexually abusing sister, after she sues him

The sister of billionaire OpenAI Chief Executive Sam Altman filed a lawsuit accusing him of sexually abusing her regularly between 1997 and 2006, prompting him and other family members to deny her claims.

In a complaint filed on Monday in St. Louis federal court, Ann Altman said the abuse occurred at the family home in suburban Clayton, Missouri, beginning when she was three and her brother was 12.

Now 30, Ann Altman said the abuse included "numerous acts" of rape, sexual assault, molestation, sodomy and battery until she was 11 or 12 years old.
