I'm looking. There was a Rumble video "Bob Hughes Maricopa County Ballot Printer Talks About AZ Audit," but It's been removed from this link: https://wethepundit.com/maricopa-county-arizona-ballot-printer-talks-facts/

and this one

and also YT:

(has anyone ever heard of these blogs before?)

which you can see were published in June 2021, before the audit was over, so he couldn't have been spilling the beans then. He might have been the one who was describing how many kinds of ballots each election requires, though. That was a good interview if someone can find it. In just this one county there may be over 600 variations, as each school and judicial and tax district will have a unique set of candidates and proposals, so it is a huge coordination problem.

Then this was one of the last things Jovan Pulitzer put ou on the watermark issue--except that the audit results were handed over later, and they did not have Pulitzer's part until much later, and that has not been revealed that I know of, and then Pulitzer got poisoned, he said. https://citizenwells.com/tag/arizona-audit-ballot-printer-id-revealed-by-microdots/
