That is professional suicide for Comey and will destroy the FBI. Not a chance. He has something of historical magnitude, he knows that already. He has to have that or he is in tremendous jeopardy himself. He couldnt take this step without knowing he can deliver.
The bigger reality is that America at this moment in in a real Constitutional Crisis. How Comey, the FBI, Congress and the American people handle and comport themselves in the coming weeks and months will determine the future of our Sacred Republic.
This really is at a tipping point.
