Former Arizona Senator Kyrsten Sinema is embroiled in a legal battle related to her relationship with a former member of her security detail. The case involves an “alienation of affection” lawsuit filed by Heather Ammel, the ex-wife of Sinema’s former bodyguard, Matthew Ammel.
Allegations and Legal Context
Heather Ammel’s lawsuit accuses Sinema of contributing to the end of her 14-year marriage to Matthew. Filed under North Carolina’s unique statute, the case permits a deserted spouse to seek damages from a third party for the breakdown of a marriage.
Details of the Relationship
According to court documents and deposition testimony, Sinema admitted her professional relationship with Matthew Ammel became romantic and sexual in 2024 while she served in the Senate. The affair spanned multiple states, including California, Arizona, New York, and Washington, D.C.
The Associated Press reported that Heather Ammel is seeking at least $75,000 in damages from Sinema. Given Sinema’s political prominence, the case has attracted considerable attention. Known for her moderate political stance, Sinema represented Arizona from 2019 to early 2025 after transitioning from a Democrat to an independent.
Testimony Highlights
During her July 31 deposition, Sinema detailed her relationship with Matthew Ammel, confirming it began romantically in May 2024. According to Fox News, the Ammels’ separation occurred on November 1, 2024, with the divorce finalized in March 2026.
Sinema confirmed the affair involved frequent communication through phone calls, emails, and encrypted messaging apps while she served in Congress. In her testimony, she recounted an incident at an Airbnb in Napa, California, where the relationship turned physical.
When questioned about texts sent to Matthew, including a picture of her wrapped in a towel, Sinema attributed them to sports-related content, given her athletic background.
A key issue in the court proceedings is whether the lawsuit can proceed, as Sinema contends the relationship occurred outside North Carolina.
Upcoming Legal Proceedings
The court’s next step involves determining whether North Carolina has jurisdiction over Sinema. On August 12, both parties submitted additional briefs, deposition excerpts, and other evidence regarding jurisdiction. Sinema has indicated plans to call live witnesses to address this issue.
U.S. District Judge David A. Bragdon will review these submissions to decide if the case can continue in North Carolina or if Sinema’s dismissal motion should be accepted. If the judge allows the case to move forward, it will progress to further discovery and potentially a trial on Heather Ammel’s claims.
