Former Clinton Secret Service Agent to Drop Tell-All of Hillary’s ‘Sickening’ Behavior

Hillary Clinton

A former Secret Service officer has penned a scathing tell-all book about Hillary Clinton, describing her "erratic, uncontrollable and occasionally violent" disposition as unfit for the presidency.

Gary Byrne, who was posted outside of Bill Clinton’s Oval Office, details an environment of terror under the former first lady whose unpredictable fits of rage permeated among White House staff.

"What I saw in the 1990s sickened me," Byrne writes in the book’s introduction, according to Page Six.

The book, Crisis of Character: A White House Secret Service Officer Discloses His Firsthand Experience with Hillary, Bill, and How They Operate, is set for release June 28—just one month before the Democratic National Convention. The exposé has already reached No. 1 on Amazon’s bestseller list due to pre-orders.

Byrne recalls Clinton often hurling obscenities at her husband, Secret Service agents, and White House staffers. He describes one "violent encounter" between the couple ahead of a national presidential address and a 1995 fight that left a blue vase shattered and a black eye on the former president.

"Hillary Clinton is now poised to become the Democratic nominee for president of the United States, but she simply lacks the integrity and temperament to serve in the office," he writes in an excerpt obtained by Page Six.

"From the bottom of my soul I know this to be true. And with Hillary’s latest rise, I realize that her own leadership style–volcanic, impulsive, enabled by sycophants, and disdainful of the rules set for everyone else–hasn’t changed a bit."

The Clinton campaign brushed aside the book’s claims, accusing Byrne of attempting to "cash in" on the 2016 race.

"It should be put in the fantasy section of the bookstore," campaign spokesman Nick Merrill told Page Six.

Byrne’s book comes a year after investigative journalist Ronald Kessler published a tell-all about Clinton’s bitter treatment of the Secret Service.

In one encounter described by Kessler, a former Secret Service officer greeted Clinton, saying, "Good morning, ma’am," to which she responded, "Fuck off."

Details of Byrne’s book arrived just two days before Clinton is set to face-off Sen. Bernie Sanders (I, Vt.) in Tuesday's crucial California primary. Polling of the state shows the two Democratic presidential contenders in a virtual dead heat.
