During an appearance on Newsmax TV's "Newsmax Prime," Ronald Kessler tells host J.D. Hayworth that if Trump makes it to the general election, he'll know what to do.
"I interviewed his longtime assistant and vice president Norma Foerderer, who went back to when he didn't even have an office," says Kessler, who has written 20 nonfiction books about the Secret Service, CIA, and the FBI."
In a 2006 Kessler article titled "The Real Donald Trump," she revealed, “Donald can be totally outrageous, but outrageous in a wonderful way that gets him coverage. That persona sells his licensed products and his condominiums. You know Donald’s never been shy, and justifiably so, in talking about how wonderful his buildings or his golf clubs are.”
The private Donald Trump, on the other hand, is “the dearest, most thoughtful, most loyal, most caring man,” Foerderer said. That caring side inspires loyalty and is one of his secrets to success.
"His office was his limousine," Kessler continued about Trump. "She was with him for almost 30 years and she said there are two Donald Trumps. One is the outrageous one who will say things to get attention as we see, and the other one is the real Donald … this very, very confident businessman who understands as he told me once that the GOP should not come across as mean-spirited towards immigrants.
"If he ever makes it to the general election, he'll know how to appeal to the general voter."
Kessler tells Hayworth a story about Trump dating back to the late 1990s, a story that he says demonstrates who Trump really is.
"When Donald opened his club in Palm Beach called Mara-a-Lago, he insisted on accepting Jews and blacks even though other clubs in Palm Beach to this day discriminate against blacks and Jews," Kessler says.
"The old guard in Palm Beach was outraged that Donald would accept blacks and Jews so that's the real Donald Trump that I know."
Kessler's latest book, "The First Family Detail: Secret Service Agents Reveal the Hidden Lives of the Presidents," comes out Tuesday. In it, he writes that Hillary Clinton is "nasty" toward the Secret Service agents assigned to protect her, while Vice President Joe Biden has ordered his aides to keep his nuclear football a mile away from him.
"She's so nasty to Secret Service agents that being assigned to her details is considered a form of punishment," Kessler says of Clinton.
Regarding Biden, Kessler says, "Joe Biden … insists that his military aide with a nuclear football — which is required in order to launch a counterstrike against a country that might attack us — be at least a mile behind in his motorcade when he goes to Wilmington, which he goes to several times a week all at our expense. He wants to have this image of a regular Joe.
"The nuclear football is a mile away, which means that it would be totally useless in the event that if Obama were taken out and there was a need to launch a counterstrike and yet the press has totally ignored that revelation in the book."
Trump's stock has risen among conservative voters in recent weeks, so much so that he was the leading Republican candidate in the results of a CNN poll released Sunday.
