James Mattis, the retired general and former defense secretary, took the stand yesterday in the criminal trial of Elizabeth Holmes, detailing how his faith in the company plummeted when a Wall Street Journal expose revealed that Theranos had been performing tests on third-party equipment.
“There just came a point where I didn’t know what to believe about Theranos anymore,” he said.
When Mattis first met Holmes in 2011 in San Francisco, he was taken by her vision and believed it could become a critical tool for the military. Later, she gave him a private demonstration, pricking his finger and showing him the company’s Edison device.
