The DOJ is doing this right: they are investigating the registration practices of the democrats, going over the voter roles and checking dead people voting and who registered them, etc.
A recount would NOT add one whit to the investigation.
By the way, what in the world is a forensic audit/recount? I have never heard that term.
You back up reported results with documents (registrations, physical ballots) then verify the documents
It's SOP in a real investigation
