I’m assuming the FBI can remove immunity for not cooperating with their investigation. Hopefully.
I believe that is the case. The person granted immunity has to live up the arrangement agreed upon. If they fail to do so, immunity may be rescinded.
Maybe the missing emails is the reason he was given immunity. Someone told him to delete the emails or not use the government system for communications with Clinton.
Pagliano was on the government payroll. Was he doing work for the government? Who was his boss? Who wrote his performance evaluation reports? We know that Patrick Kennedy, Under Secretary for Management, hired Pagliano at the behest of Hillary. As someone who worked for the State Department for 28 years, I find the hiring of a minor IT tech by the U/S highly unusual. if not unprecedented.
From all reports, Pagliano is cooperating with the government. There is a reason why Pagliano pleaded the 5th before Congress and this could be the smoking gun. You don't offer immunity without getting something in return. Pagliano is singing like a canary.
It will be interesting to learn if the FBI was able to recover all the documents from Hillary's server, including the ones deleted.
