Not only did they explain that Russia influenced the election, it was the main topic of hours of conversation, about two hours (?) of which I liveblogged which specifically mentions how Russia influenced the election. Let me go find that chain. It was all written in real time… and yes, they kind of fact-checked it during the hearing, although Comey wasn’t really too responsive. But from the conversation, they were talking specifically about Russia and how Russia interferes in the elections; both men, Rogers and Comey, said it was ongoing, unlikely to stop, and that it would happen in 2018 and 2020 and was happening in Europe right now, although they were working to help avoid it in Europe, with their intel.
They explained that it was unprecedented in scope, that Wikileaks helped, that it was cyber-based, hacking-based, and propaganda based, and also that Russia tried to probe (but unsuccessfully) computers. They also thought there could be other forms of interpersonal influence, and that Putin categorically wanted Trump to win.
