As it stands, about 32,000 emails from Clinton's private server have been leaked by Wikileaks. Assange has yet to comment on how many new emails will be released or when they will be published.
While he thinks there will be enough to indict Clinton, he doesn't think it will happen under Attorney General Loretta Lynch. He does think "the FBI can push for concessions from the new Clinton government in exchange for its lack of indictment."
Specifically, Assange revealed the leaked emails show that Hillary Clinton overrode the Pentagon's reluctance to overthrow sovereign Libyan leader Muammar Gaddafi in 2011, and that "they predicted the post-war outcome would be what it is, which is ISIS taking over the country."
