This week Twitter, Facebook, and Google will testify publicly before the US Congress about how the Russian government manipulated public opinion during the 2016 US election. Today (Oct. 31) they will be grilled on terrorism and crime by a Senate Judiciary subcommittee, and tomorrow (Nov. 1) they will testify in front of the Senate and House Intelligence Committees.

Until now, the companies have been tight-lipped about political manipulation on their platforms—but it’s all about to come out. As an idea of what is to come, ahead of the hearings today it was revealed that over 126 million Facebook users in the US were exposed to Russian-created political content.
