Former Senator Kyrsten Sinema's private life has entered the public spotlight in a highly unusual legal battle that tests the boundaries of personal conduct, public service, and centuries-old marriage laws. The case highlights how rare legal statutes can still hold public figures financially accountable for their private relationships, reigniting a broader debate over the legal liabilities of elected officials.
What Happened
Former U.S. Senator Kyrsten Sinema of Arizona has provided sworn testimony detailing a romantic and sexual relationship with her former personal bodyguard, Matthew Ammel, while he was still married. The details emerged from a July 31, 2026, deposition connected to a lawsuit filed by Ammel's ex-wife, Heather Ammel.
Heather Ammel is seeking at least $75,000 in damages under North Carolina's "alienation of affection" law. Often referred to as a "homewrecker" law, this rare legal statute allows a deserted spouse to sue a third party for intentionally interfering with and destroying a marriage. The Ammels, who were married for 14 years and have three children, finalized their divorce in March 2026.
According to court documents, Sinema testified that the romantic relationship began around Memorial Day weekend in 2024 at an Airbnb in Napa, California. "We were staying at an Airbnb in Napa, California. We were outside. Matt kissed me. We went inside and had sex," Sinema stated under oath. She noted that they were staying at the property with her friends and another member of her security detail.
The relationship continued with subsequent intimate encounters in several other locations throughout 2024. Sinema testified that they were intimate in her hotel room in New York City while attending the wedding of CNN anchor Jessica Dean in June. She also detailed having sex with Ammel at her Washington, D.C., apartment in July, and again during a fundraising trip to Aspen, Colorado, in August.
Sinema's legal team is actively fighting the lawsuit. They successfully moved the case to federal court and are challenging its validity on jurisdictional grounds, arguing that the relationship occurred almost entirely outside of North Carolina. Furthermore, her attorneys are challenging the constitutionality of the centuries-old marriage tort itself.
- The Lawsuit: Filed by Heather Ammel, seeking at least $75,000 in damages.
- The Accused: Former Arizona Senator Kyrsten Sinema, who served from 2019 to early 2025.
- The Bodyguard: Matthew Ammel, hired to Sinema's security detail in 2022.
- The Law: North Carolina's "alienation of affection" statute, which allows civil suits against third parties for destroying a marriage.
- The Defense: Sinema's legal team argues North Carolina lacks jurisdiction and is challenging the constitutionality of the law.
Why It Matters
This lawsuit brings a rare, centuries-old legal doctrine back into the national spotlight. Alienation of affection laws have been abolished in most U.S. states, but they remain active in North Carolina and a handful of other jurisdictions.
The case also raises significant questions about the private conduct of public officials. Because Matthew Ammel was employed as Sinema's bodyguard and later appointed to a congressional fellowship in her office, the line between personal relationships and the use of official staff has drawn intense scrutiny. It forces a public conversation about where an official's private life ends and their public accountability begins.
What Happens Next
U.S. District Judge David A. Bragdon is currently reviewing supplemental briefs and evidence filed by both parties. The judge will decide whether the case should be dismissed due to lack of jurisdiction, as Sinema's team has requested, or if it will proceed to trial. If the motion to dismiss is denied, the case will advance further into the discovery phase, potentially bringing more communications, travel logs, and testimony into the public record.
What We Still Don't Know
- Will the federal court rule that it has jurisdiction over Sinema, given that she argues the romantic encounters occurred outside of North Carolina?
- How will this lawsuit impact the ongoing debate over the constitutionality of "alienation of affection" laws in the few states where they still exist?
- Were taxpayer funds or official Senate resources used to facilitate any of the travel or lodging where the romantic encounters took place?
