Theranos trial: Elizabeth Holmes took former US general’s blood

A former US defence secretary has described how he lost faith in the technology company that took his blood as part of testimony in the case against disgraced Theranos founder, Elizabeth Holmes.

James Mattis, who was on the company’s board, said he was initially “amazed” by Ms Holmes’ blood tests.

But by 2016 he “didn’t know” what to believe after she was accused of fraud.

Ms Holmes, 37, denies the charges that she deceived patients and investors.

She could face 20 years in jail if found guilty.
