Kyrsten Sinema hit with ‘homewrecker’ lawsuit over alleged affair with ex-bodyguard

More than merely “handsy,” details have emerged about former Arizona Sen. Kyrsten Sinema’s alleged drug-fueled, concert-going homewrecker relationship with her security guard.

After bailing on the Democratic Party to consider herself independent in 2022, Sinema announced her intent against seeking reelection in 2024, officially departing Congress in January 2025. Amid the political upheaval, the first openly bisexual woman elected to the Senate was allegedly pursuing sexual trysts with multiple members of her security detail, including one marriage-ending affair that has since prompted a lawsuit seeking at least $25,000 in damages.

Filed in Moore County, North Carolina at the end of September 2025, Heather Ammel’s suit alleges that Sinema violated the state’s “alien of affection” law after her husband, Mark Ammel, father of their three children, began working for her security detail.

“Beginning in or prior to 2023, Defendant, with actual knowledge of the Marriage between Plaintiff and Mr. Ammel, began to willfully and intentionally seduce, entice, and alienate the affections of Mr. Ammel, and began to wrongfully and maliciously deprive Plaintiff of the warmth, companionship, love, affection, consortium, society, financial contributions, services, and attention of Mr. Ammel,” the suit read in part.

Included among the allegations in the court document, the plaintiff contended that Sinema had sexual dalliances with multiple members of the security detail, and that she had plied Ammel, a retired member of the U.S. Army struggling with PTSD, traumatic brain injuries and substance abuse via alcohol, drugs, travel and dining.

“In the fall of 2023, Defendant’s head of security resigned from her position. Prior to leaving, Defendant’s head of security expressed to Mr. Ammel she had concerns Defendant was having sexual relations with other security members. She encouraged Mr. Ammel to leave with her, but Mr. Ammel decided to stay due to the financial security of the job,” the suit alleged at one point before contending that Ammel “appeared uncomfortable” after returning from a trip to Napa Valley, California alone with Sinema and that had anyone “seen them together on the trip, it would have appeared as if they were on a romantic getaway.”

In addition to messages about sexual intercourse describing “missionary style with the lights on, and Defendant stated ‘Boring!'” the suit alleged that Sinema sent the Plaintiff’s husband messages via the Signal app, including one of herself wrapped in a towel, that “exceeded the bounds of a normal working relationship and were of romantic and lascivious natures.”

A message sent to Ammel about Sinema missing him was said to have been intercepted by the plaintiff after her husband had begun working as a personal security guard and Senate staff member. The plaintiff responded, “are you having an affair with my husband? You took a married man away from his family.”

The court documents contend that Ammel acknowledged Sinema had been “handsy” with him at the March 2024 Extra Innings Festival in Phoenix, Arizona and that he had been invited into Sinema’s hotel room during a trip to San Francisco “and they stayed together for hours.”

She was also said to have invited him over to her apartment several times, including after purchasing a theragun so she could “work on his back.”

In addition to trips together, including a time where Ammel had stayed with Sinema alone at her Scottsdale, Arizona home after being her “security and guest for a wedding” in New York City — around the same time he’d stopped wearing his wedding ring over concerns about “public optics” — Sinema had arranged multiple concert experiences for the married man and his family.

On one occasion, the plaintiff had been a guest at a U2 concert while another instance had seen the plaintiff’s child attend a Green Day concert. The whole family attended a Taylor Swift concert with Sinema the same month the senator was challenged on the affair as the plaintiff expressed “concern for the Children.”

Additional allegations claimed that Sinema had offered to “guide [Ammel] through a psychedelic experience” if he brought “MDMA drugs on a work trip”

The senator would go on to pay for psychedelic treatment for the veteran, according to the lawsuit, and it was Ammel who was said to have initiated separation and divorce proceedings from his wife after he had been confronted about the alleged affair.

The plaintiff has requested a jury trial for any issues permitted to go to trial in addition to whatever relief the court “deems just and proper.”
