Also from above link:
Court papers also list another FinCEN employee as a co-conspirator, noting that this person exchanged more than 300 messages with the reporter via an encrypted messaging application. This person has not been charged and was not named in the court papers, and was identified only as an associate director at FinCEN to whom Edwards reported.
According to court papers, federal investigators obtained a court order to monitor the calls to and from the associate director’s personal cellphone, and that monitoring captured the frequency of contacts with the reporter via the encrypted messaging application. Court papers do not detail the contents of those messages.
“According to court papers, federal investigators obtained a court order to monitor the calls to and from the associate director’s personal cellphone, and that monitoring captured the frequency of contacts with the reporter”
So busted.
Clearly, the nets have been out for a while - a professional job.
