A new book from Amy Chozick offers inside details about the Hillary Clinton campaign, detailing an alleged tirade the candidate went on during debate prep.

“Aides understood that in order to keep it all together onstage, Hillary sometimes needed to unleash on them in private,” an excerpt from the book reads.

At one point Clinton allegedly delved into a tirade against then-candidate Donald Trump.

‘You want authentic, here it is!’ she’d yelled in one prep session, followed by a fuck-laced fusillade about what a ‘disgusting’ human being Trump was and how he didn’t deserve to even be in the arena.”

The book is titled “Chasing Hillary: Ten Years, Two Presidential Campaigns and One Intact Glass Ceiling.”
