Flynn would not have sacrificed himself to have his info go nowhere. That would have been thought out very carefully beforehand, I am sure.
I was not aware the referrals were based on information from Flynn. In any event, he could not control what Mueller does with the info. The DOJ caught Awan with the goods and swept it under the rug. They covered up the Weiner laptop and Hillary’s emails in the SDNY. If Flynn gave them info they couldn’t ignore, that would be where they would send it to die.
But all of it is conjecture and speculation until we know more.
