A group of national Olympic committees that has been investigating the matter said it hasn’t arrived at any mutually acceptable agreement yet because it needs to investigate further individual accusations of wrongdoing that would involve Russian athletes who have been supposed to go to Pyeongchang. Only then, the group said, it could recommend punishment on case-by-case basis and make suggestions as to whether the scandal is so overwhelming that it should lead to the expulsion of the entire Russian delegation, permitting only those athletes whose records are clean to participate, but not under their national flag.
The IOC is basically investigating two individual matters: individual athletes and their use of performance enhancing drugs, and the Russian government involvement.
The government involvement came to light officially for the first time during the 2014 Winter Olympic Games in Sochi, Russia. Unofficially, it has been known, and often proven beyond any reasonable doubt, since the Soviet Union first took part in the Olympic Games in 1952 in Helsinki, Finland.
