A good technical support representative keeps notes. They are time and date stamped and contain the topic, names of the participants, what each one said and the conclusion of the conversations. In Comey’s position as head of the FBI I believe such files do exist. However, I would not be able to accept just select files about a conversation without seeing the complete file of all conversations he has had since becoming head of the FBI. Too easy to make one up the night before he testifies.
Our misrepresentatives in Congress should demand to see all the files, if they exist, or accept none. They are all secret. Maybe they will see why Hillary’s lying was never prosecuted as a bonus. Washington and the liberals have had six months to tell us what the Russians did to change the election and, amazingly, not one thing has ever leaked out about it because apparently there was nothing to leak.
