PHILADELPHIA (CBS) — Author Ronald Kessler defends secret service agents and makes some sensational claims about former Presidents in his new book, The First Family Detail: Secret Service Agents Reveal the Hidden Lives of the Presidents.

Kessler told Chris Stigall on Talk Radio 1210 WPHT that the recent struggles of the agency detailed in the media are more the fault of management culture than individual agents.

“The culture that has led to this corner-cutting, it’s a culture within the management, not among the agents. Agents…are patriots. They sign up to take a bullet for the President. The management has the attitude of covering up, dismissing problems, retaliating against agents that do reports problems. Unfortunately, President Obama’s decision to appoint Joseph Clancy, a veteran agent, to continue as Director, has just continued the same culture, because he really represents that culture.”

He reports some very scandalous stories in the book, including allegations of former President Clinton carrying out liaisons with another woman when his wife, former Secretary of State Hillary Clinton, is not around.

“He has a blonde, busty mistress, and she’s been code named Energizer by agents. This is unofficially, but that is what they call her…She comes in to the Chappaqua [NY] home whenever Hillary leaves. The details coordinate to make sure they don’t cross paths. She, unlike Hillary, is very nice to the agents. She’ll bring cookies.”

Kessler also contends the Clintons’ relationship is only based on their desire to return to the White House in 2016.

“Agents say that it’s a business relationship. It’s not a marriage at all. It’s a total fake, like everything else about Hillary. It’s just a big show and a scam.”

And the agents assigned to Hillary’s detail, says Kessler, don’t usually look forward to the assignment.

“Hillary Clinton pretends to be this champion of the little people — she’s gonna help the middle class, she’s compassionate. But the reality behind the scenes is she treats her agents and others less powerful than she is with contempt. In fact she’s so abusive to her agents that being assigned to her detail is considered a form of punishment,” he said. “That tells you something about her character.”

While some may argue that Kessler’s accounts are nothing but gossip, he stands by his claims. He said that many of the agents in the book allowed for their names to be printed along with their stories.

“I don’t make up things. You can tell from the accounts that they’re very detailed, for example with the Energizer agents are instructed not to ask for her ID or to ask her to sign in even though any other Clinton relative for example has to sign in,” he said.

The book doesn’t just focus on the Clintons. Kessler looks at previous administrations including those of John F. Kennedy, Lyndon Johnson, and Richard Nixon.

Before ending his conversation with Stigall, he threw in one more detail from the book: “By the way, Biden likes to skinny dip which offends female Secret Service agents.”
