That is the entire point of the whistleblower's whistleblowing. WHAT CHUMP DISCUSSED WITH THE UKRAINIAN LEADER.
So that is chump's answer to the question. He did not say he did not say what we are told he said. He did not deny it. He simply said it didn't matter.
Of course to you prodons that is a perfectly logical and extremely stable genius intelligent reply. Why should it matter what the chump says to anyone at any time for any reason?
HE IS ABOVE THE LAW so all is acceptable!
