The odd thing is your need to tell people prior to the interview that it was happening at all. With specific contact info for the journalist. Why would you do that? What harm in waiting? Did you want him to be contacted? Was it just to brag that something important was happening?
If you were advising someone else in your position
@Miss Tommie Jayne Wasserberg , would you tell them to share all before the fact?
Really, even someone very fair minded and uninvolved would probably called it as bragging.
Odd.
