BEIJING — The news here Friday in the bubble — er, closed loop — was all about how International Olympic Committee president Thomas Bach came down hard, and appropriately, on the 15-year-old Russian skater Kamila Valieva’s “entourage.”

“We are following the rule of law and we are feeling at the same time with a minor, with a 15-year-old girl who obviously has a drug in her body that should not be in her body and the ones who have administered these drugs in her body — these are the ones who are guilty,” Bach said, referring to Valieva’s Dec. 25 positive test for trimetazidine.

A few moments later, Bach turned to a World Anti-Doping inquiry into the people around Valieva. She crumbled on the ice Thursday night, sliding from first to fourth and breaking into tears, only to be met by her coach, Eteri Tutberidze, asking why she gave up, a moment that Bach called chilling and disturbing: “I hope that this inquiry will bring clarity so that the full truth is coming to light that the people who are responsible for this, that they will be held responsible for this — that they will be held responsible for this in the right way and when I say the right way, I say in the strongest possible way.”
