Oak Dowling will guide us through the key elements of the trial so far. Holmes is now facing charges of wire fraud and a significant portion of the trial has been in-depth scientific and financial detail, including testimony from several former lab workers who grew concerned about the company's technology. But former defense secretary Jim Mattis, who was on the board, took the stand to say he would have had a different view of the company if he had known its limitations. And pages of text messages between Holmes and her then-boyfriend Sunny Balwani—who was also the company’s president—were read aloud in court. In an unexpected twist, a juror was excused for playing too much Sudoku.
