>> for me as someone that's been covering this story and this case is the work that went into this and the penetration that the fbi and our intelligence partners were able to -- they successfully penetrated this entire operation. they knew everything they were doing, and it's so detailed and so specific in this indictment. and it takes a lot for the fbi and the department of justice to reveal these kinds of details because it essential gives away what they know. >> it sounds like intercepts, cyber communications, they were in there. >> they were in there. they knew where they were located in this town in st. petersburg. there were two individuals that were part of this operation that traveled to the united states. they knew when they came here, perhaps granting them visas knowing they were coming here for the reasons they were coming here. it was stunning the level of detail that went into this piece of document. this is rare. and it's rare if the u.s. government to allow this kind of information to be made public.
