Bryan Pagliano was Clinton’s computer technician, and he made an immunity deal with the Justice Department in late 2015.
Several days earlier his lawyers revealed to federal judge Emmet Sullivan that it was a limited “derivative use” immunity deal.

Several days later, Sullivan will agree to keep the details a secret.
