The House passed a bill this month that would order the Pentagon’s inspector general to investigate whether the Defense Department weaponized ticks. Stanford University science writer Kris Newby, in a new book called “Bitten,” hints that such experiments may have led to the rapid spread of Lyme disease. Newby says that congressional inquiry into the matter “is exactly what I wanted to happen.” And CQ Roll Call’s defense writer John Donnelly explains what Congress has asked the Pentagon  to do and why many experts doubt it caused the public health crisis.
