Comey: "An unauthorized disclosure of a FISA is extraordinary and we are taking it very seriously." Did he just confirm existence of FISA?

Initial social media reporting from the JUL timeframe indicated a FISA warrant had been issued to investigate the two servers talking to each other...one in Alfa Bank Moscow and one in the Trump Tower...

That investigation is still evidently ongoing..especially since Alfa Bank attempted via a press release to "blame unnamed hackers" for creating the illusion of a communication....

BTW...long after the info became public..you would think they would have stated that back in JUL 2016...
