From an August 8 speech to the Southwest Broward Republican Organization:
QUESTIONER: With regard to the October surprise, what would be your forecast on that given what Julian Assange has intimated he's going to do?
ROGER STONE: Well, it could be any number of things. I actually have communicated with Assange. I believe the next tranche of his documents pertain to the Clinton Foundation but there's no telling what the October surprise may be.
