What did turbin's secret memo amount to?
A dud.
It was such a lame attempt that I don't even remember what it was about.
Turbin had a memo - which I believe was an agenda for a meeting - on which Roberts had made handwritten notes. One of the agenda items (something about Iran/Contra?)apparently distressed Turbin, and he thought that he was going to nail Roberts.
Roberts said "I did not participate in that meeting". Game over.
It came at the end of Turbin's first turn yesterday, if I recall. Check the transcript.
