Recurring disinformation narrative claiming that there is no proof of Russian interference in the elections in Western countries and the US - see examples here and here.
The story is the latest link in a chain of denials which Moscow has issued regarding its involvement in the 2016 presidential election in the United States and employs the long-established charge of Russophobia which the Kremlin uses to deflect criticism, however legitimate.
Before the Mueller report was published, Russian meddling in the 2016 election had already been established by US intelligence agencies. Thus, the Special Investigation was primarily concerned with "whether any Americans […] joined the Russian conspiracies to influence the election" (p.2).
The report explicitly identifies "numerous links between individuals with ties to the Russian government and individuals associated with the Trump Campaign" (p. 9). A number of these individuals later "made false statements about those contacts and took other steps to obstruct" the probe (p. 180). The report's conclusions, therefore, do nothing to absolve the Russian government. Further debunk here.
