Same reason they went after Flynn.
To prevent his knowledge from being associated with justice against a malevolent infiltration of the DOJ, by creating a narrative of 'Flynn as defendant'.
Raffensperger same pattern.
Open investigations INTO the very same sources of knowledge of election fraud, to prevent their knowledge from becoming information associated with justice against ahahaha but that WAS how it was supposed to work with people in the dark and misled by fake news and fake school and fake Georgia "SoS".
