Theranos’ former lab director has become a central focus of early questioning in Elizabeth Holmes’ criminal trial. Late last week, the defense continued its cross-examination of one of the prosecution’s key witnesses, attempting to paint Dr. Adam Rosendorff as unreliable.

Three facts could damage Rosendorff in the eyes of the jury. Whether those facts diminish his prior testimony depends largely on Holmes’ defense team. Given the damning facts Rosendorff laid out during the prosecution’s questioning, that will be a difficult task. But discrediting key witnesses is something all defenses have to attempt.
