SAN FRANCISCO — Elon Musk returned to federal courtroom Monday in San Francisco to testify in a category motion lawsuit filed by Tesla traders alleging he misled them with a tweet.

The tweet resulted in a $40 million settlement with securities regulators, claimed he had lined up the financing to take Tesla non-public in a deal that by no means got here near taking place.

The trial hinges on the query of whether or not a pair of tweets that Musk posted on Aug. 7, 2018, broken Tesla shareholders throughout a 10-day interval main as much as a Musk admission that the buyout he had envisioned wasn’t going to occur.
