Have you found a source for this?
No... I didn't know there was a question until I read on in this thread, I just did a quick OCR for anyone wanting to quote it.
Here is a story in The Hill from November of last year. Looks legit. The Hill does not provide a link to the report but it does say -- The use of audits was a step recommended by the Senate Intelligence Committee to secure elections in volume one of its bipartisan report on Russian interference efforts in 2016.
It is posted here, but the poster says 'DHS’s Press Release
Notes: This release is not public. I can share the link all I want, and unless you have an AP OneWire account through your employer, you simply will not be able to view it. Nobody else will allow this to go public either, so I decided to leak it. We deserve to know what’s going on.'
So I guess that is the best link we will get.
