Hillary Clinton has repeatedly laid responsibility for her defeat in the 2016 presidential election on “Russian interference” that helped her opponent. Her claims have never been corroborated by any evidence.
Additionally, in April 2019 Special Counsel Robert Mueller stated that he had found insubstantial evidence to prove that Trump had colluded with the Kremlin.
Recurring pro-Kremlin disinformation denying Russian interference in the 2016 US presidential election in particular, and whitewashing the Kremlin's meddling in Western democratic processes generally.
Available evidence suggests that Russian meddling the 2016 US presidential poll - which specifically aimed to damage Clinton's campaign and aid her opponent - did affect the outcome of the vote, particularly in three critical swing states where Trump's victory margins were the thinnest.
