This is the best summary I could come up with:

Tesla is facing scrutiny over its mysterious "Project 42" that was believed internally to involve building a glass house for Elon Musk, according to a recent report from The Wall Street Journal.

The publication said, citing people familiar with the issue, that federal prosecutors are investigating whether Tesla used its own funds for Musk's personal use, and is looking into how much the company has spent on the initiative, as well as its purpose.

The US Attorney's Office for the Southern District of New York issued subpoenas to multiple current and ex-Tesla employees, some of which have been asked to appear in court in September, Bloomberg reported on Wednesday.

The project appeared to be for a "dramatic glass-walled building" and concept plans showed differing designs and features, but included residential elements like bedrooms, according to the report.

At the time, the internal inquiry into the order had targeted Omead Afshar, an executive leading Tesla's Texas factory, Bloomberg reported last year.

On Wednesday, the publication reported that federal prosecutors were seeking information related to internal communications with Afshar, who was said to be involved in purchasing the construction materials.
