Gary Byrne says the likely Democratic nominee is too “erratic, uncontrollable and occasionally violent” for the presidency, according to excerpts obtained by Page Six.

“What I saw in the 1990s sickened me,” Byrne writes in the introduction of “Crisis of Character: A White House Secret Service Officer Discloses His Firsthand Experience with Hillary, Bill and How They Operate.” The book, due out June 28, already holds the top spot on Amazon's best-seller list.

“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 said.

“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 rule set for everyone else — hasn’t changed a bit.”

Clinton’s campaign on Sunday dismissed Byrne’s account, saying his new book is an attempt at profiting off the former first family.

“Gary Byrnes joins the ranks of Ed Klein and other ‘authors’ in this latest in a long line of books attempting to cash in on the election cycle with their nonsense,” spokesman Nick Merrill said. "It should be put in the fantasy section of the book store.”
