"Although the FBI eventually took possession of the servers, Strzok continued, the possession was "based upon the negotiation of Department of Justice attorneys for consent."
"A significant filter team" was employed at the FBI, Strzok said, to "work through the various terms of the various consent agreements." Limitations imposed on agents' searches included date ranges, and names of domains and people, Strzok said, among other categories.
The agreement was reached, Strzok said, because “according to the attorneys, we lacked probable cause to get a search warrant for those servers and projected that either it would take a very long time and/or it would be impossible to get to the point where we could obtain probable cause to get a warrant.”"
