What happened

OpenAI CEO Sam Altman is slated to testify in federal court in Oakland, California, on Tuesday as part of the trial in Elon Musk's lawsuit against the artificial intelligence company.

Why it matters

Altman is expected to take the stand after Bret Taylor, the chairman of the board at OpenAI, concludes his testimony, his lawyers told Judge Yvonne Gonzalez Rogers on Monday.

Common ground

Taylor was called as a witness on Monday afternoon, where he answered questions about the role of OpenAI's board and the company's corporate structure.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
