"All"

[underpants]

Well they have their talking point and they are going to stay with it until the end.
30 years from now those of lucky to still be around will hear the same thing

"Why don't they release ALL the memos?"

Nice. Can't be disproved because:
a. there is a finite amount of memos but there have to be truckloads of memos so that isn't really practical
b. there are actual national security concerns (not just "national security" being used as cover for not having proof of an assertion) so ALL the memos simply can't be released.

This is delaying the inevitable but as long as they hold out and extend it they think they can convince people of something different than we already know.
