Another set of emails from Wikileaks reveals more about the Clinton campaign.

FOX's Jon Decker has more:

The latest trove of documents released by WikiLeaks includes thousands of pages of alleged emails sent to and from Clinton Campaign Chairman John Podesta.

Among the revelations: Clinton advisers explored a campaign strategy at least two years before she entered the presidential race; Clinton aides seemed unprepared for the insurgent campaign of Bernie Sanders; and Clinton allies expressed concern last year about a possible presidential run by Vice President Joe Biden.

One email sent by a longtime aide to Bill Clinton described Chelsea Clinton as a "spoiled brat" who has a "lack of focus in her life."

The Clinton campaign has not verified the authenticity of the emails.
