Schemer or Naïf? Elizabeth Holmes Is Going to Trial.

The trial for the founder of Theranos, the once high-flying blood testing start-up, will cap a saga of Silicon Valley hubris, ambition and deception.

SAN FRANCISCO — After four years, repeated delays and the birth of her baby, Elizabeth Holmes, the founder of the blood testing start-up Theranos, is set to stand trial for fraud, capping a saga of Silicon Valley hubris, ambition and deception. Jury selection begins on Tuesday in federal court in San Jose, Calif., followed by opening arguments next week. Ms. Holmes, whose trial is expected to last three to four months, is battling 12 counts of fraud and conspiracy to commit wire fraud over false claims she made about Theranos’s blood tests and business. In 2018, the Department of Justice indicted both her and her business partner and onetime boyfriend, Ramesh Balwani, known as Sunny, with the charges. Mr. Balwani’s trial will begin early next year. Both have pleaded not guilty.
