NB: The Government Accountability Office is not subject to the APA and the FOIA, but nevertheless has its own public disclosure procedures at 4 C.F.R. pt. 81.
The Government Accountability Office published a proposed rule revising procedures for the public disclosure of records in today's issue of the Federal Register. While the agency is not legally required to solicit comment, it is accepting feedback on the rule until September 25, 2017.
