That's a good question.
Considering they didn't know it was him when they made the request (why request the unmasking if you know who it is?) you have to wonder why was he on so many calls that piqued the interest of the intelligence community.
I think they absolutely knew it was him. He has had cross-hairs on him since he was fired by Obama.
I’m sure you have to go to a particular place to “unmasK’ someone and looking at the dates, it was a parade on Dec 16th. (I might have to go back and look again at the dates.)
Boy you dont get it, do you? They didnt unmask Flynn.
They were actively spying on him. The so-called unmasking was a ruse.
They knew who they were unmasking because they had been monitoring all his calls illegally.
Wake up.
