Russian doping allegations
In December 2014, German public broadcaster
ARD aired a documentary which made wide-ranging allegations that Russia organized a state-run
doping program which supplied their athletes with
 In November 2015, the
World Anti-Doping Agency (WADA) published a report and the
International Association of Athletics Federations (IAAF) suspended Russia indefinitely from world track and field events.
In May 2016,
The New York Times published allegations by the former director of Russia's anti-doping laboratory, Dr.
Grigory Rodchenkov, that a conspiracy of corrupt anti-doping officials,
Federal Security Service (FSB) intelligence agents, and compliant Russian athletes used banned substances to gain an unfair advantage during the Games. Rodchenkov stated that the FSB tampered with over 100 urine samples as part of a
cover-up, and that a third of the Russian medals won at Sochi were the result of doping.
 On 18 July 2016, an independent investigation commissioned by
World Anti-Doping Agency concluded that it was shown "beyond a reasonable doubt" that the
Ministry of Sport, the
Federal Security Service (FSB) and the Centre of Sports Preparation of the National Teams of Russia had "operated for the protection of doped Russian athletes" within a "state-directed failsafe system" using "the disappearing positive [test] methodology". According to the
McLaren Report, the Disappearing Positive Methodology operated from "at least late 2011 to August 2015". It was used on 643 positive samples, a number that the authors consider "only a minimum" due to limited access to Russian records.
On 9 December 2016, Canadian lawyer
Richard McLaren published the second part of his
independent report. The investigation found that from 2011 to 2015, more than 1,000 Russian competitors in various sports (including summer, winter, and Paralympic sports) benefited from the cover-up.
 Following the release of the McLaren report, the
International Olympic Committee announced the initiation of an investigation of 28 Russian athletes at the Sochi Olympic Games.
La Gazzetta dello Sport reported the names of 17 athletes, of whom 15 are among the 28 under investigation.
 As of late December 2017, 13 medals had been
stripped and 43 Russian athletes had been disqualified for competition in 2018.
 The number of athletes under investigation rose to 36 (and eventually 46) in December.
Russia has denied the existence of a doping program with
Vladimir Putin blaming the United States for "using the Olympics to meddle in the
Russian presidential election".
On 5 December 2017, the
IOC announced that the Russian Olympic Committee had been suspended from the 2018 Winter Olympics with immediate effect. Athletes who had no previous drug violations and a consistent history of drug testing were to be allowed to compete under the
Olympic Flag as an "Olympic Athlete from Russia" (OAR).
 Under the terms of the decree, Russian government officials were barred from the Games, and neither the country's flag nor anthem would be present (the Olympic Flag and
Olympic Anthem would be used instead).
 On 20 December 2017 the IOC proposed an alternative logo for the OAR athletes' uniforms (shown on right).
 IOC President
Thomas Bach said that "after following due process [the IOC] has issued proportional sanctions for this systematic manipulation while protecting the clean athletes".
As of January 2018, the IOC had sanctioned 43 Russian athletes from the
2014 Winter Olympics and banned them from competing in the 2018 edition and all other future Olympic Games as part of the
Oswald Commission. All but one of these athletes appealed against their bans to the
Court of Arbitration for Sport (CAS). The court overturned the sanctions on 28 athletes, meaning that their Sochi medals and results were reinstated, but decided that there was sufficient evidence against eleven of the athletes to uphold their Sochi sanctions. The IOC said in a statement that "the result of the CAS decision does not mean that athletes from the group of 28 will be invited to the Games. Not being sanctioned does not automatically confer the privilege of an invitation" and that "this [case] may have a serious impact on the future fight against doping". The IOC were careful to note that the CAS Secretary General "insisted that the CAS decision does not mean that these 28 athletes are innocent" and that they would consider an appeal against the court's decision. The court also decided that none of the 39 athletes should be banned from all future Olympic Games, but only the 2018 Games. Three of the 42 Russian athletes that originally appealed are still waiting for their hearing, which will be conducted after the 2018 Games.
An original pool of 500 Russian athletes was put forward for consideration for the 2018 Games and 111 were immediately removed from consideration. The remaining athletes had to meet pre-games conditions such as further pre-games tests and reanalysis from stored samples. Only if these requirements were met would the athletes be considered for invitation to the Games. None of the athletes who had been sanctioned by the Oswald Commission were still in the pool at this stage.
 The final number of neutral Russian athletes invited to compete was 169
 and, after speed skater
Olga Graf dropped out, the eventual total was 168.

In the past, the
Vladimir Putin and other officials had stated that it would be an embarrassment for Russia if its athletes were not allowed to compete under the Russian flag.
 However, his spokesman later revealed that no boycott had actually been discussed prior to the IOC's decision.
 After the announcement,
Ramzan Kadyrov, the
head of Chechnya, announced that none of the
Chechen athletes would be permitted to participate under a neutral flag.
On 6 December, Putin stated that his government were prepared to allow Russian athletes to compete at the Games as individuals, but there were still calls from other Russian politicians for a boycott.
Gennady Zyuganov, leader of the
Communist Party of the Russian Federation, proposed to send fans to the Games with a Soviet
Sergey Lavrov, the
Russian Minister of Foreign Affairs, suggested that the United States "fears honest competition";
 while Vladimir Putin was of the opinion that the United States had used its influence within the IOC to "orchestrate the doping scandal".
 He called the IOC decision an unfair "collective punishment", saying "It all looks like an absolutely orchestrated and politically motivated decision. For me, there are no doubts about this."
The popular Russian newspaper
Komsomolskaya Pravda reported that 86% of Russians opposed participating in the Olympics under a neutral flag.
 Despite the OAR designation, many Russian fans still attended the Games, wearing the Russian colours and chanting "Россия!" ("Russia!") in unison, in an act of defiance against the ban.
 After the games, Russian figure skater
Evgenia Medvedeva revealed in an
Instagram post that the Russian tricolor was hidden on the OAR medal ceremony uniforms underneath a white fur scarf buttoned on the front of the jacket.
International Ice Hockey Federation voiced support for allowing the full participation of "all clean Russian athletes" in the 2018 OIympic Winter,
 calling on the IOC to not impose “collective punishment”.
The IOC's decision was heavily criticized by Jack Robertson, who was primary investigator of the Russian doping program on behalf of the
World Anti-Doping Agency (WADA). Robertson argued that the IOC had issued "a non-punitive punishment meant to save face while protecting the [IOC's] and Russia's commercial and political interests". He also highlighted the fact that Russian
whistleblowers proved beyond doubt that "99 percent of [their] national-level teammates were doping". According to Robertson, "[WADA] has discovered that when a Russian athlete [reaches] the national level, he or she [has] no choice in the matter: [it is] either dope, or you're done". He added "There is currently no intelligence I have seen or heard about that indicates the state-sponsored doping program has ceased."
 It was also reported that Russian officials intensively lobbied US politicians in an apparent attempt to secure Dr. Grigory Rodchenkov's
 (Rodchenkov being the main whistleblower).
The CAS decision to overturn the life bans of 28 Russian athletes and restore their medals was fiercely criticised by Olympic officials, including
Thomas Bach who said the decision was "extremely disappointing and surprising". Whistleblower Rodchenkov's lawyer stated that "the CAS decision would allow doped athletes to escape without punishment",
 also that "[the CAS decision] provides yet another ill-gotten gain for the corrupt Russian doping system generally, and Putin specifically".
