Mattis not only served on Theranos’s board during some of the years after he’d retired from military service, while it was perpetrating the scheme, but he earlier served as a key advocate of putting the company’s technology (technology that was, to be clear, fake) to use inside the military while he was still serving as a general. Holmes settled the SEC case, paying a $500,000 fee and accepting various other penalties, while Balwani is fighting it out in court. (Holmes and Balwani are both battling criminal fraud charges.)
