“F*** OFF,” HILLARY REPLIED:

‘​Good morning, ma’am,” a member of the uniformed Secret Service once greeted Hillary Clinton.

“F*** off,” she replied.

That exchange is one among many that active and retired Secret Service agents shared with Ronald Kessler, author of First Family Detail, a compelling look at the intrepid personnel who shield America’s presidents and their families — and at those whom they guard.

Kessler writes flatteringly and critically about people in both parties. Regarding the Clintons, Kessler presents Chelsea as a model protectee who respected and appreciated her agents. He describes Bill as a difficult chief executive, but an easygoing ex-president. And Kessler exposes Hillary as an epically abusive Arctic monster.

“When in public, Hillary smiles and acts graciously,” Kessler explains. “As soon as the cameras are gone, her angry personality, nastiness, and imperiousness become evident.” He adds: “Hillary Clinton can make Richard Nixon look like Mahatma Gandhi.”

Note this conclusion: Kessler’s “astonishment at Hillary Clinton’s inhumanity should reverberate inside every American’s head. As he told me: ‘No one would hire such a person to work at a McDonald’s, and yet she is being considered for president of the United States.'”

Well, McDonald’s expects its employees to be competent and have certain minimum skills.
