Seems pretty open ended. I think there is plenty of room to creep, especially with FWFWFWFW: Grandpa Barr calling the shots.
"The OIG, in response to requests from the Attorney General and Members of Congress, is examining the Department’s and the FBI’s compliance with legal requirements, and with applicable DOJ and FBI policies and procedures, in applications filed with the U.S. Foreign Intelligence Surveillance Court (FISC) relating to a certain U.S. person. As part of this examination, the OIG is also reviewing information that was known to the DOJ and the FBI at the time the applications were filed from or about an alleged FBI confidential source. Additionally, the OIG is reviewing the DOJ’s and FBI’s relationship and communications with the alleged source as they relate to the FISC applications. If circumstances warrant, the OIG will consider including other issues that may arise during the course of the review."
