Musk has widened his court battle with OpenAI by demanding documents from Helen Toner, a former OpenAI board member who was the point person in last year's OpenAI "palace fight" that led to the brief firing of Altman, OpenAI's chief executive. Musk, one of OpenAI's earliest investors, demanded that Toner hand over her departure from the OpenAI board, according to a Washington, D.C., Superior Court filing.
