But we are pretty certain that Flynn's name came in via the FBI.
Flynn’s name was unmasked in an intercept of his December 29, 2016, call with Russian Ambassador Sergey Kislyak.
"Sally Yates...learned about that call from Obama himself at an Oval Office meeting on Jan. 5, 2017."
From whom???
Was Flynn's call given to us from foreign Intel source?
"Comey said the bureau found the intercept as it was trying to figure out why the Kremlin had decided not to respond to the decision to expel 35 Russian spies"
