Longtime Trump associate Roger Stone and New York radio host Randy Credico reportedly discussed WikiLeaks just before the secrets-leaking website published stolen emails from Democratic officials during the 2016 campaign.

Stone has denied that he had prior knowledge of WikiLeaks’ plan to release the emails. But in a series of conversations via text message provided to NBC News by Stone, Credico told Stone in August 2016 that “Julian Assange has kryptonite on Hillary.”
