The Russian embassy also said it was "no surprise" that the investigation delivered "no tangible result" in its own massive 120-page study, released online Friday, even the title of which pulled no punches — The Russiagate Hysteria: A Case of Severe Russiaphobia.

The publication blasted a list of "groundless accusations" repeated since Trump's 2016 election, including allegations of Russian election meddling, the Kremlin's supposedly being behind the DNC hack, as well as Trump's working with Russian intelligence. 

It concluded in the wake of the Mueller report:

The investigation... didn't show any real evidence to back up claims of Moscow's cyberattacks and attempts to "subvert democracy".

Though Mueller's report failed to deliver on much of what the mainstream hyped over the years, it did point to efforts of Russian "interference" in US elections and alleged that Russian military intelligence was complicit in "hacking" the DNC.
