 In February 2017, All-Russia Athletic Federation vice-president Andrey Silnov held a press conference in Moscow alongside a former Soviet athlete who said that East German successes due to state-sponsored doping are legitimate results of "good pharmacology" and should not be condemned.Later that month, WADA stated that evidence against many individuals named in the McLaren report might be insufficient because the Moscow laboratory had disposed of doping samples and Russian authorities were not answering requests for additional evidence.An IAAF taskforce chaired by Rune Andersen published an interim report in April 2017.
