Theranos’ Elizabeth Holmes Takes the Stand in Surprise Move

Theranos founder Elizabeth Holmes took the stand in her fraud trial on Friday—which will allow prosecutors to grill her next week. The former Silicon Valley golden girl is accused of soaking investors who sunk hundreds of millions of dollars into a blood-testing machine that turned out to be a dud. Defense lawyer Kevin Downey asked her if she believed the invention would work as promised. “I did,” Holmes testified during her one-hour stint in the witness box.
