“The Cyber Hack is far greater in the Fake News Media than in actuality,” Trump tweeted late Saturday morning. “I have been fully briefed and everything is well under control. Russia, Russia, Russia is the priority chant when anything happens because Lamestream is, for mostly financial reasons, petrified of discussing the possibility that it may be China (it may!).”

Trump added that “there could also have been a hit on our ridiculous voting machines during the election, which is now obvious that I won big, making it an even more corrupted embarrassment for the USA.”

This isn't a Russian cyber attack, its a Chinese attempt to fix the election.
A lot more can happen yet. We still have another month to go.
