Politico has this on the FBI's recent filing in a FOIA suit -- in the declaration the FBI details the steps it took to locate emails sent from non government email accounts by former Secretary of State Hillary Clinton.
The amazing thing is the detail about federal grand juries that are provided by the FBI. In most FOIA cases, grand jury information is highly redacted and exempt pursuant to FOIA exemption 3 to protect the secrecy of the grand jury. Here, however, the FBI describes its use of grand juries in its investigation of the emails as well as its later use of grand juries in another case - this one likely that into the investigation of former Rep. Anthony Weiner.
It's not apparent the effect this will have in future FOIA litigation but what is striking about this is the level of detail about the use of grand juries provided by the FBI, which is not something usually seen in a FOIA case in a public declaration.
