Catherine the Great!
Yep, you got that correct, Catherine II, also known as Catherine the Great (Екатери́на Вели́кая, Yekaterina Velikaya), Empress of Russia from 1762 until 1796.
That's because the only thing which made Donald Trump president was the electoral college, an institution created by the US Constitution (Article II, Section 1, Clauses 2-4). So, if there really WAS any "Russian" influence in the process that made Trump president of the US, it would have had to have been produced during the reign of Catherine the Great!
The Fact is Hillary Clinton won the popular vote with 65,853,516 (48.5% votes) to Trump's 62,984,825 (46.4% votes), but lost in the electoral college by receiving 232 (43.1%) of the electoral votes to Trump's 306 (56.8%) votes.
Of course, it is far easier to blame the Russians for this defeat than it is to address the real issues behind Clinton's loss.
Although, that is a strategy that is sure to backfire since any claims of "Russian" interference result in the faults of the Clinton Campaign: her being a weak candidate, DNC misconduct, and pretty much everything that was common knowledge to Sanders' supporters and Clinton opponents.
Any real discussion of Clinton's loss must include the faults of the US system of elections: especially the radical overhaul of the electoral college, which was supposed to have prevented foreign interference in the US presidential process ( The Federalist Papers, No 68).
It is blatantly obvious that the Electoral College serves no useful purpose, but that won't be addressed as long as people refuse to address the real cause of Trump's becoming president.
Then again, any real investigation of the US election would be a threat to the current Democrat-Republican duopoly. The duopoly thrives on the illusion that US elections are somehow "democratic", but it is hard to make that claim when an institution designed to be anti-democratic is allowed to continue its existence.
