Federal Times has this on the recent revelation that the EPA under former head Scott Pruitt created a special office inside the General Counsel's Office to process politically charged and/or complex FOIA requests. This revelation came from a transcript released by Rep. Elijah Cummings (D-MD) on July 13, 2018.
There is nothing wrong with creating a special office to assist in the processing of complex requests; the problem lies when the special office is involved in requests that are only "political" and are not complex. Unfortunately, there is little known about exactly what this special office did and if its purpose was to just block the release of information that could damage the EPA politically (even though this would be hard to do in that the EPA under Pruitt was very successful in damaging the agency without the release of any FOIA information). Rep. Cummings has subpoenaed more information on this program; I'm sure others will make FOIA requests for it. Once this information is released, the public and Congress will know exactly if and how this program's purpose was to block transparency at the EPA.
