Theranos Whistleblower and Company Insiders Testify at Elizabeth Holmes Trial
The second week of Elizabeth Holmes' fraud trial has concluded, marked by testimony from former Theranos colleagues. The star witness was perhaps Erika Cheung, the person who blew the whistle to regulators. She testified that there were red flags in the company's testing practice and described Theranos' technology as inadequate for testing patient samples. Surekha Gangakhedkar, a former company senior scientist, also took the witness stand.
