How many people voted for Hiltery Rotten Clinton because of fakenews about manmade global warming?
How much collusion was there between MSM and DNC HRC to coordinate messaging and news items?
The "fake news" on Facebook were those ads raising doubt that Hillary's 30,000 deleted emails were about weddings and yoga classes. They were ads questioning the integrity of the Clinton Foundation, suggesting that this foundation might be a slush fund for the Clinton family.
This is why you can be assured that when the MSM talks about Russian "fake news" on Facebook, we'll never see the actual examples.
