WikiLeaks will publish information that could damage the presidential candidacy of Hillary Clinton, the website’s co-founder Julian Assange told Fox News Wednesday.

Assange described the information as “significant” and said that the leak would include “unexpected angles.” Assange said that the impact of the leaks would depend on how the public and media respond to the leak when asked by Megyn Kelly whether he thought the leaks would move the needle in an election that seems to be going in Clinton’s favor.

WikiLeaks released a trove of emails earlier this summer that led to the resignation of Democratic National Committee Chair Debbie Wasserman Schultz and other top party officials.
