Antidoping officials from at least 10 nations and 20 athlete groups are preparing the extraordinary step of requesting that the entire Russian delegation be barred from the Summer Olympics over allegations of a state-sponsored doping program, according to email correspondence obtained by The New York Times.
The antidoping officials and athletes were expected to pressure Olympic leaders on the matter as soon as Monday — less than three weeks before the opening ceremony in Rio. They were waiting for the results of an investigation into claims published in The Times of a state-sponsored doping program conducted by Russian officials at the 2014 Sochi Olympics.
