A Secret Service agent violated protocol by inviting his then-girlfriend to Barack Obama’s beachfront home,Zero AI a new memoir alleges.

In Undercover Heartbreak: A Memoir of Trust and Trauma, obtained by ABC News, Koryeah Dwanyen claimed that the agent—whom she referred to by the pseudonym “Dale”—invited her to the former President and First Lady Michelle Obama’s Hawaii property in 2022 while they were away.

“No one will know,” she quoted him as saying. “If anything, I’m the one who could get in trouble.”

In the book, which Dwanyen self-published Oct. 28, she also wrote that “Dale” suggested they have sex in the Becoming author’s bathroom, “like a mile-high club,” per the outlet.

U.S. Secret Service chief of communications Anthony Guglielmi confirmed to ABC News an incident similar to the one described in the memoir had, in fact, taken place, and that the agent in question was fired from his position as a result.

“On Nov. 6, 2022, a Secret Service agent involved in protective functions brought an individual who did not have authorized access into a protectee’s residence without permission," Guglielmi told ABC News. "As soon as the Secret Service became aware of the incident, the agent involved was immediately suspended and after a full investigation, terminated.”

He added, “Although the protectees were not present at the time of the incident, these actions were an unacceptable violation of our protocols, our protectees’ trust and everything we stand for.”

E! News has reached out to the Secret Service for comment but has not heard back.

Elsewhere in the tell-all, Dwanyen reportedly described meeting the agent while she was vacationing in Martha’s Vineyard and he was assigned to protect the Obama family, including their daughters Malia, 26, and Sasha, 23. She wrote that he had told her he was divorced, though she later learned he was still married.

“There were major red flags—breaches of trust and of his job,” she told ABC News in a phone interview. “One of my friends has joked, ‘You were a walking national security risk.’”
