First, former U.S. ambassador to Russia Michael McFaul explains what we know for sure about Russian interference in our elections:
To influence the outcome of our presidential election and stir general doubt about our democratic processes, Russian operatives: (1) stole and published information, (2) deployed their state-controlled media to reach American voters on the airwaves and social-media platforms, (3) bought ads on Facebook, (4) deployed an army of bloggers and bots to push opinions and fake news, (5) offered the Trump campaign alleged incriminating information on its opponent, Hillary Clinton, and even (6) probed our computers and networks used to count the vote. This is what we know so far; the investigations are not complete.
Next, McFaul lays out specific steps the United States could be taking right now to stop Russia's intervention in our domestic affairs and electoral processes, concluding "Unless we adopt a comprehensive strategy to reduce and stop cyber-interventions, they will happen again in the future."
