SAN FRANCISCO - Elon Musk told jurors on Monday (Jan 23) he was sure he had locked up financial support from Saudi investors in 2018 to take his electric car maker Tesla Inc private, and could even have used his stake in rocket company SpaceX to fund a buyout.

At a trial in San Francisco federal court, the billionaire, who said he was tired from a lack of sleep, spoke quietly and calmly during roughly five hours of testimony.
