In a court filing today, lawyers for Sam Altman said that his sister Ann Altman’s “false statements” had tarnished his reputation and caused emotional pain.

His attorneys also claimed Ann Altman sued him “for the improper purpose of pressuring him to accede to her demands for unrestricted financial support”.

Ann Altman’s attorney didn’t immediately respond to a request for comment.

In January, Ann Altman alleged that Sam Altman abused and manipulated her while they were growing up in Missouri in the late 1990s to early 2000s.

She claimed the abuse began when she was 3 years old and the last instance allegedly occurred when he was an adult but she was still a minor.

At the time, Sam Altman posted a statement on behalf of himself, his mother and brothers, calling the claims “utterly untrue”.
