JIM ACOSTA: I think this is a key test for the transition team of President-elect Trump. I think the only thing worse than perpetuating fake news is denying real news, and reality is that Russia was behind this. That is the assessment from our intelligence community. And if Donald Trump and his transition team can't acknowledge that, there's going to be a real problem, I think, in the intelligence community, because they're going to be wondering, at some point, when we bring information to you, are you going to operate off of it?
