....Certainly at least some small number of those would be emails to or from Abedin, wouldn’t they?.....
The biggest problem I see is the foot dragging by the FBI. The IG has known for months that classified info was on Hillary’s server and thumb drive and no move by the FBI to secure either. Giving people a lot of time to delete and coordinate actions.
Why the time lag?
In a properly functioning universe, this would be in order to tap phones and intercept communications that would implicate the conspirators. Perhaps the FBI has already recruited some of the conspirators and they are wearing wires. Linda Tripp wore one, didn't she?
