They revealed the DNC was trying to tip the scales towards her in their primary which was unsavory but I don’t recall wikileaks having anything to do with the classified emails…
although the main purpose of their release timing was to bury, drown, and distract from a certain other piece of info that had come out - bye bye claim to like transparency lol.
And the email server in hindsight also seems quaint - a scandal from a time of innocence and naivety. At the time it seemed overblown too, but now it’s downright quaint. Non stop private email and encrypted messenger app use followed that, and then we all know how classified docs have gone lately.
