# Former Senator Kyrsten Sinema Faces “Alienation of Affection” Lawsuit: What California Families Should Know About This Rare Legal Claim

## Understanding the Lawsuit Against Former Arizona Senator Kyrsten Sinema

Former U.S. Senator Kyrsten Sinema is facing a lawsuit filed by Heather Ammel, the ex-wife of Matthew Ammel, who served as part of Sinema’s security detail. The lawsuit, filed in Moore County, North Carolina, seeks at least $75,000 in damages under North Carolina’s “alienation of affection” law—a legal claim that allows former spouses to sue third parties they believe caused the breakdown of their marriage.

## What Is an “Alienation of Affection” Lawsuit?

If you’re wondering “what is alienation of affection?” or “can I sue someone for breaking up my marriage?”—you’re not alone. This type of lawsuit is one of the rarest in U.S. family law today.

North Carolina is one of only a handful of states that still recognize “alienation of affection” claims, which permit a former spouse to pursue legal action against someone they believe intentionally interfered with their marriage.The lawsuit must demonstrate:

The marriage had genuine love and affection

A third party’s actions destroyed that affection

The third party acted with malicious intent or knew the person was married

## Key Details of the Ammel v. Sinema Case

According to court documents, Heather Ammel alleges that:

Matthew Ammel was hired as part of Sinema’s security team after retiring from the U.S. Army in 2022

He traveled with Sinema to multiple destinations including Napa Valley, Las Vegas, and Saudi Arabia

In early 2024, Heather discovered “romantic and lascivious” messages between her husband and Sinema via the Signal messaging app

Matthew stopped wearing his wedding ring and received a position as a national security fellow in Sinema’s Senate office

Sinema allegedly paid for psychedelic treatment for Matthew, who has struggled with PTSD, substance abuse, and traumatic brain injuries from his military service

The lawsuit was filed in late 2025, and Sinema has since requested that the case be moved from state court to federal court.Neither Sinema nor her attorney have responded to requests for comment.
