"If you thought 2016 was a big WikiLeaks year, 2017 will blow you away," WikiLeaks tweeted on Monday, giving no hints as to what may be in store. The tweet, featuring a clip from a Clint Eastwood spaghetti western showdown, also included a link to its website's donation page so people can help the site "prepare for the showdown.

2016 was another game-changing for the whistleblowing site, as it delivered a massive trove of documents over the 12-month period. These included over 50,000 emails from John Podesta, Hillary Clinton's campaign chair and more than 27,000 emails from the Democratic National Committee, which confirmed the DNC worked against Democratic presidential candidate Bernie Sanders, favoring Clinton, and ultimately led to the resignation of then-DNC chair Debbie Wasserman-Schultz.
