So this was on the IG web page, the first I've heard of it. It's nice because it represents rebuilding from the ground up and destruction of the old.
Review of the DOJ's and FBI's Planning for a Future FBI Headquarters Facility
The OIG is conducting a review that will assess the DOJ’s and FBI’s planning for a future FBI Headquarters facility. The review will include an examination of DOJ’s and the FBI’s progress in its planning, their assessment and consideration of the previously proposed plan to move FBI Headquarters to a suburban location, and their assessment and consideration of the plan to demolish the J. Edgar Hoover Building and construct a new facility on that site.
