This is Comey's "City on a Hill" speech. It will be a focal point of all the documentaries made about Trump's so-called presidency and the Russian interference in the 2016 election:
The reason this is such a big deal is we have this big messy wonderful country where we fight with each other all the time, but nobody tells us what to think, what to fight about, what to vote for except other Americans. And that's wonderful and often painful. But we're talking about a foreign government using technical intrusion and lots of other methods tried to shape the way we think, we vote, we act. That is a big deal. And people need to recognize it. It's not about Republicans or Democrats. They're coming after America, which I hope we all love equally. They want to undermine our credibility in the face of the world. They think that this great experiment of ours is a threat to them, and so they're going to try to run it down and dirty it up as much as possible.
That's what this is about. They will be back, because we remain, as difficult as we can be with each other, we remain that shining city on the hill, and they don't like it.
