If you’re Hillary Clinton, (God forbid), what two words would you use to reply to a friendly “Good morning, ma’am,” from a member of the uniformed Secret Service?

Would you believe, “F— off”?

Of course you’d believe it. That epithet is attributed to Hillary by Ronald Kessler in his book “First Family Detail,” which revolves around the Secret Service agents who protect America’s First Family.

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

Hillary has been noted for her rudeness for years; some examples allegedly include:

"Where is the G-damn f***ing flag? I want the G-damn f***ing flag up every f***ing morning at f***ing sunrise."

"You sold out, you mother f***er! You sold out!"

'F**k off! It's enough that I have to see you ****-kickers every day, I'm not going to talk to you too!! Just do your G*damn job and keep your mouth shut.'

"You f***ing idiot."

"If you want to remain on this detail, get your f***ing ass over here and grab those bags!"

Kessler’s book quotes former Secret Service agent Lloyd Bulman alleging,  “Hillary was very rude to agents, and she didn’t appear to like law enforcement or the military. She wouldn’t go over and meet military people or police officers, as most protectees do. She was just really rude to almost everybody. She’d act like she didn’t want you around, like you were beneath her.”

Another agent: “Hillary didn’t like the military aides wearing their uniforms around the White House. She asked if they would wear business suits instead. The uniform’s a sign of pride, and they’re proud to wear their uniform. I know that the military was actually really offended by it.”

Former agent Jeff Crane: “Hillary would cuss at Secret Service drivers for going over bumps.”

According to Kessler, White House usher Christopher B. Emery returned a call from former First Lady Barbara Bush asking about computer troubleshooting. Emery helped Mrs. Bush twice, prompting Hillary to fire him.

Former FBI agent Coy Copeland said Hillary had a “standing rule that no one spoke to her when she was going from one location to another. In fact, anyone who would see her coming would just step into the first available office.”

“F— off!”

Hillary Clinton replying to Secret Service agent greeting her “Good morning, ma’am,”

Hillary elitist? Try this: when she was running for the Senate, Hillary was scheduled to visit an upstate New York 4-H Club. One agent recalled that when Hillary saw the farmers and their cows, she was furious. The agent said, “She turned to a staffer and said, ‘What the f - - - did we come here for? There’s no money here.’ ”

Yet another former agent protecting Hillary: “Hillary never talked to us . . . Most all members of first families would talk to us and smile. She never did that.”

Finally, one agent concludes, “We spent years with her. She never said thank you.”
