It should be obvious that Comey's notes of his meeting(s) with Trump are or little or no value, in spite of what Rep. Schiff says:
All they would do is help continue the "he said, he said" narrative. Is Comey more credible than Trump? I don't think so.
What we DO need is Trump's tape(s) of their conversation(s). That would prove once and for all what actually was said.
And they almost certainly would end the Trump presidency.
