I may be mistaken about which conversation you referred to, with McCarthy involved, But, very similar conversation surfaced involving Paul Ryan and Mike Pence, and their staff. Do you remember that? There was a transcript with who said what. Fake, I don’t know.
I posted a transcript many months ago.. I’d have to do serious digging to find when I posted it. I iwsh search words could find individual posts on FR but they only seem to find threads/titles. That would make self searches easier
