Some choice excerpts:
Again another "fish expedition" -just because they are media doesn't mean that the memos would shed light on specific government activities….
DON2014F-0387: this one is specific enough that we may be able to deny. However, I want to talk with the FBI, as they may have "all emails during that time, in their possession."…
