Two straightforward facts published in another Globe story:

"The Obama advisers grew suspicious that perhaps there had been a secret deal between the incoming team and Moscow, but when they asked the FBI if a quid pro quo had been discussed on the call, the answer came back no, according to one of the officials cited by The New York Times. "

"...it’s not unusual for incoming administrations to have discussions with foreign governments before taking office."

Flynn did nothing wrong in having discussions with foreign officials prior to Trump assuming office. Nor, according to the FBI, did he negotiate anything concerning sanctions or anything else. However, someone or some faction within the US intelligence community did commit a felony by leaking confidential government information. 

There's a lot of commenters here with something on their faces, and it's not egg.
