Sam Altman’s estranged younger sister Ann Altman filed a lawsuit against the OpenAI CEO on Monday, accusing him of childhood sexual abuse.

On Tuesday afternoon, Sam Altman posted a statement on social media signed by his mother Connie and younger brothers Max and Jack denying the allegations.

In Monday’s complaint, Ann Altman alleges that her older brother sexually abused her multiple times in the 1990s and 2000s, beginning when she was 3 years old, resulting in post-traumatic stress disorder and physical injuries.

“At all times relevant here, defendant Sam Altman influenced and manipulated plaintiff Ann Altman into believing that the above sexual acts were her idea, even though she and defendant were less than five years old when the sexual abuse began also “I’m almost a teenager,” the complaint states.

In addition to the physical and psychological effects of the alleged abuse, Ann Altman “suffered a loss of enjoyment of a normal life as a result of her emotional injuries,” the lawsuit says.

The lawsuit seeks unspecified damages in excess of $75,000 in addition to legal fees.

In Sam Altman’s post from Tuesday, he and the family write:

“Our family loves Annie and is very concerned for her well-being. It is very difficult to care for a family member who is struggling with mental health issues,” the statement said. “Over the years, we have tried in many ways to support Annie and help her find stability, following professional advice on how to be supportive without enabling harmful behaviors.”

The statement shows that the Altman family offered Ann Altman, who is nine years younger than Sam, monthly financial support and “tried to seek her medical assistance.” safe apartment, but can’t sell it immediately.”

“Still, Annie continues to demand more money from us. “In this spirit, Annie has made deeply hurtful and completely untrue allegations about our family, particularly Sam,” the statement continued. “We have chosen not to respond publicly out of respect for their privacy and ours. However, she has now taken legal action against Sam and we feel we have no choice but to address this matter.”

Ann Altman had previously made her allegations public through posts on the social media platform X, formerly Twitter.

The Altman family’s statement on Tuesday denied the allegations against Sam Altman and other members of the Altman family and said: “All of these allegations are completely untrue.
