Matt Taibbi, American journalist associated with Rolling Stone among others, has made a list of 25 accusations for “Russian interference” or “Russian disinformation” which, on closer inspection, turn out to be false. See https://taibbi.substack.com/p/master-list-of-official-russia-claims.
Among them are stories of close contacts between Trump and Russian agents, Hilary Clinton’s allegations of Russian cyberattacks, FBI allegations of other cyberattacks, etc etc, which have been widely reported in the media.
It is certainly possible, even probable, that Russia engages in such things, as all other states do. Says Taibbi. But surely it is telling that the false accusations are so abundant? If there were plenty of genuine ones, it would not be needed.
