I want to revisit my response to you on this. What Flynn was discussing COULD be a crime of conspiracy, if a quid pro quo was offered and received on the call. The fact he was fired so quickly could increase that likelihood, as they may not have fired him if the subject had only very briefly been mentioned, and they thought they could (and wanted to) make that argument in his defense.
What kind of quid pro quo are you talking about? Conspiracy to do what?
