Former Sen. Kyrsten Sinema of Arizona admitted under oath that she carried on a "romantic and intimate" relationship with a married member of her own Senate security detail. The admission came in a sworn declaration filed as part of a lawsuit brought by the bodyguard's then-wife, who says Sinema deliberately destroyed her 14-year marriage.
Sinema did not contest the affair. Her legal strategy instead focuses on getting the case thrown out on jurisdictional grounds, arguing that a North Carolina federal court has no authority over a relationship that took place entirely outside the state's borders.
The bodyguard, Matthew Ammel, served on Sinema's protective detail while she was still in office. His wife, Heather Ammel, filed suit alleging deliberate interference in their marriage. The relationship began in May 2024 in California and, according to the court filing, spanned multiple states, including New York, Colorado, Arizona, and Washington, D.C.
While Sinema's sworn declaration acknowledged the relationship itself, the original lawsuit paints a far more troubling picture. According to the complaint, Sinema allegedly flew Ammel on expensive solo trips and covered the cost of psychedelic therapy for him. The lawsuit also alleges she told him to bring MDMA on a work trip so she could facilitate a drug experience for him, as The Daily Caller reports.
Sinema has not publicly addressed these specific allegations. The court filing focused narrowly on the relationship and the jurisdictional question.
The two communicated through phone calls, emails, and Signal, the encrypted messaging app. At one point, Heather Ammel interrupted a Signal conversation between Sinema and her husband and confronted the senator directly.
Heather Ammel has said her husband suffered from PTSD and traumatic brain injuries tied to his Army service. The implication of the lawsuit is clear: Sinema exploited a position of extraordinary power over a vulnerable subordinate, and a military family paid the price.
The lawsuit also flags a broader concern. According to the complaint, Sinema's former top security official raised alarms in 2023, a full year before the Ammel affair allegedly began, over her alleged sexual involvement with other members of her protection team.
No names or details about those earlier allegations have been made public. The security official is unnamed in court filings. But if the allegation holds, the Ammel relationship wasn't an isolated lapse. It was part of a pattern involving the very people entrusted with protecting a sitting U.S. senator.
Think about what that means for the integrity of a Senate security operation. The people on a protective detail are supposed to be singularly focused on one job. When the principal is allegedly involved with members of that team, every professional boundary collapses. Chain of command, loyalty, discretion: all compromised.
North Carolina is one of only a handful of states that still allows alienation of affection claims, a legal cause of action that lets a spouse sue a third party for deliberately interfering in a marriage. The doctrine is old, but it remains active, and North Carolina courts have delivered multimillion-dollar verdicts in such cases.
That legal landscape explains why the lawsuit landed in a North Carolina federal court after initially being filed in late 2025. The complaint seeks $25,000 in damages, though in cases like these, that figure often represents a procedural threshold rather than the full amount at stake.
Sinema's attorneys are making a straightforward play: the affair happened in California, New York, Colorado, Arizona, and D.C. None of it happened in North Carolina. Therefore, they argue, a North Carolina court has no business hearing the case.
It's a defensible legal argument. It's also a remarkably clinical response to what amounts to an admission, under oath, of an affair with a married subordinate who was employed to protect her.
Washington spent years lecturing the country about power imbalances in professional relationships. The MeToo movement. Workplace conduct standards. The insistence that when someone holds authority over another person, consent operates differently and scrutiny must be higher.
Those principles apparently stop applying when the person in power is a former U.S. senator. Sinema held enormous authority over the members of her security detail. They served at her direction. Their professional futures were tied to her satisfaction with their performance. That is a textbook power imbalance, and the silence from the usual corners is deafening.
If a male senator had admitted, under oath, to a "romantic and intimate" relationship with a female member of his security detail whose spouse said she suffered from PTSD and traumatic brain injuries from military service, the story would lead every cable news broadcast for a week. Advocacy organizations would issue statements. Colleagues would be asked to condemn it on camera.
Sinema gets a Washington Post tweet and a jurisdictional hearing.
The jurisdictional fight will determine whether this case proceeds in North Carolina or gets dismissed on procedural grounds. If Sinema's motion succeeds, Heather Ammel could potentially refile in a state where the relationship actually took place, though few other states offer the same alienation of affection cause of action.
The broader allegations, the psychedelic therapy, the MDMA, and the 2023 warnings about other members of the protection team remain unresolved. Sinema addressed none of them in her sworn declaration. They sit in the complaint, unanswered.
Heather Ammel lost a 14-year marriage. Matthew Ammel, whatever his own culpability, was a man dealing with the scars of military service who was placed in the orbit of a powerful senator with, if the lawsuit's allegations prove true, a history of crossing professional lines with her protectors. Sinema's legal team is focused on which courthouse hears the case. The facts of what she actually did remain uncontested.
She admitted it. She just wants to make sure no court is allowed to do anything about it.
