I can imagine a way to convert that into illegal spying, removing the statutory defense available in 50 USC 1809(b). Either way, perjury of "illegal snooping," the penalty is 5 years max., $10,000 fine. This statute might also be used to capture leaking of the Flynn phone call with Kislyak.
I don't think it's necessary to discredit Buzzfeed. The material in the FBI interviews of Ohr is on the right track.
The issue I see is that people will be disappointed if US government interfering with the election, and nearly throwing it, boils down to perjury or illegal snooping or illegal leaking, and nothing more.
Thank you
