They should still call him and let him take the fifth. Meanwhile, has the FBI or anyone else(think Kerry’s State Cleaning Service) bothered to collect all employment records and all records of his work on these computer servers. Invoices and other paperwork will show the server(s) used. Probably will show the multiple servers used and the ones we don’t know about yet. Anyone not checking is giving Hillary a pass.
It would be interesting to see if such paperwork exists. Did Pagliano submit detailed invoices? Did the Clintons send him a 1099? Knowing the Clintons, I suspect the answer is no to both. It is possible that Pagliano did not bother to complete a Schedule C and report the income on his 1040, either.
Platte River was probably a bit more formal. They are a company, they probably send invoices. But such invoices can be very vague: “Computer services, 37 hours at $85 a hour, total $3145”.
