Whoever was in the meeting with Obama on Jan 5th knew of Flynns name, as Obama himself didn't have the authority to unmask:
GOWDY: All right, so that's four. The NSA, FBI, CIA, Main Justice. Does the White House have the authority to unmask a U.S. citizen's name?
COMEY: I think other elements of the government that are consumers of our products can ask the collectors to unmask. The unmasking resides with those who collected the information.
And so if Mike Rogers's folks collected something and they sent it to me in a report and it says U.S. person number one and it's important for the FBI to know who that is, our request will go back to them. The White House can make similar requests of the FBI or of NSA but they can't on their – they don't own their own collect and so they can't on their own unmask. I got that about right?
ROGERS: No, that's correct.
You're Amazing Admiral Rogers. Here's him describing the process of unmasking:
