Hillary Clinton and her team projected the appearance of unity during the 2016 campaign, but a new book detailing her election loss suggests things got pretty heated behind the scenes.

The Hill has an excerpt from the book, called "Shattered: Inside Hillary Clinton's Doomed Campaign, by Jonathan Allen and Amie Parnes," which will be released in April 18th, and according to one passage, both Hillary and Bill Clinton got into it with top advisors at times on the campaign trail.

There was one incident during debate prep where strategist Jake Sullivan was reportedly the target of Hillary's frustrations after critiquing one of her mock answers.

There's also another section in which the authors claim Bill told top advisors on a conference call, "Voters want to hear about Hillary's plans for the economy, and you're not making that happen," he allegedly said, adding, "Now, do your damn jobs."

The passage then claims she closed the call by agreeing with her husband and adding, "Get it straight."

"Shattered" is set for release on April 18, 2017.
