Keep this in mind about anyone who may have "unmasked" Flynn

The Justice Department went to Trump and warned him that Flynn was subject to blackmail by the Russians, according to reports. They may have said more. Trump sat on that information for almost 3 weeks without doing anything. Flynn continued to be present at high security events, he still had his job and was privy to state secrets....

Then someone went to the press and revealed that Flynn had been compromised through, minimally, lying about his contact with the Russians - but probably much more.

Then Flynn got fired, roughly within a day AFTER the press ran with the story.

When the President won't act to protect our nation sometimes someone else steps into the breech. That person is a hero, whether or not they "leaked" Flynn's classified identity by unmasking it in the intercepts.
