"You know, everyone's tired of Russia. We're tired of Russia. But let's be really clear, this was a war conducted by Russia on a number of platforms, not just the hacking, but using Facebook and buying $100,000 worth of ads and creating some 470 Facebook pages. It also was troll farm that were conducted out of St. Petersburg, where they were using every imaginable means they had at their disposing to undermine our democracy," Speier said.



Speier said Russians may have "hacked into our election systems."



"The most critical issue that we have to deal with is, to what extent they hacked into our election systems. And I have grave concerns about their ability to get in," she said.
