Judge in Chauvin case warns that a mistrial may be called if the prosecutors use their rebuttal witness to attack defense claims around CO poisoning. It’s a procedural thing - prosecutors can’t get two bites of the apple when you’re putting on your case, but prosecutors are trying to claim that the defense opened the door by claiming this. Defense argues that they had already indicated that they might go this route pre-trial.

Prosecution would like to recall pulmonologist Dr. Tobin to bring the point home. Defense doesn’t want that to happen. #DerekChauvinTrial #GeorgeFloyd
