I’ll extend this a little. There are two red flags here, IMO. I don’t trust the nurse’s account, because she knows she screwed up and might be trying to shift blame away from herself. I also don’t trust the CDC account, because they may also be trying to shift blame away from themselves. The only way I will be convinced is to have a transcript that I can read.
I understand what you’re saying. If the conversation was recorded, a transcript would be helpful. (However, can we really trust anything from the CDC at this point?)
IMHO, if the CDC believed the transcript could play in their favor, they probably would’ve released it to the media.
Maybe they’ll still release the transcript (after they “correct” it, of course). Their credibility is a joke now.
