personnel found to have provided performance-enhancing drugs to minors should be banned for life and personally, i also think that they should be in prison. earlier today, an ioc official said that valiyeva blamed the positive drug test on a mix-up with her grandfather's medication. we have no further detail on that, but these are the facts we do know, which is that the drug she tested positive for, other olympians have been disqualified for also testing positive for it. also, doctors say that the drug she tested positive for, endurance and improves blood flow. all of this as other figure skaters and athletes are saying that allowing her to compete is making a mockery of clean competition, it is tainting a moment that other skaters have spent so many years preparing for. kate? >> thank you so much for that reporting. joining me now from beijing,
