I've never even hinted at anything related to "treason" with Flynn.
Go back and see if you can find reports of the sequence of events there. From what I've seen, Flynn didn't seek advice from the Trump campaign, but from the transition team -- which meant it was AFTER the election.
Can we agree that campaign team and transition team are basically the same people separated by a few weeks and Mueller has tried to criminalize the activities of both ...Flynns activities during transition being Muellers aim since what Gen Flynn did as a private consultant before being named as NatSecAdvisor is far harder to criminalize ( what...he gathered intel and wrote a report about Gulen ....for a private company! and it wasnt Fusion GPS)
