Elizabeth Holmes expresses some remorse as she takes the stand in her criminal trial

Biotechnology entrepreneur Elizabeth Holmes, a former billionaire accused of engineering a massive medical scam, expressed some remorse while on the witness stand Tuesday, but denied trying to conceal that her company's blood-testing methods weren't working as she had promised.
In her third day of testimony during the high-profile criminal trial, Holmes acknowledged making some mistakes as CEO of Theranos, a company she founded in 2003 when she was just 19.

Holmes, now 37, also made it clear that she never stopped believing that Theranos would revolutionize health care with a technology that was supposed to be able to detect a wide range of diseases and other problems by testing just a few drops of blood, even when confronted with adversity.
