(Ken Silva, Headline USA) Former U.S. Sen. Kyrsten Sinema is being sued for having sex with her security guard and breaking up his family in the process. Depositions from the case were filed in federal court on Wednesday, revealing details about the affair ahead of a legal hearing set for Wednesday.
The bodyguard’s ex-wife, Heather Ammel, is suing Sinema for “alienation of affection”—a North Carolina law that says someone can be held financially liable for initiating an affair. Sinema, for her part, has said that her relationship with the bodyguard, Matthew Ammel, only started after he and Heather were separated, and that the relationship didn’t occur in North Carolina.
In her July 31 deposition, Sinema said the first time she had sex with Matthew was in May 2024, which was while Matthew and Heather were still married.
“We were staying at an Airbnb in Napa, California. We were outside. Matt kissed me. We went inside and had sex,” Sinema said.
Kyrsten Sinema's ex-boyfriend lied about when their affair started. When called out for it, he admitted to lying during his divorce proceedings because he was afraid he'd lose custody.

Sinema’s testimony contradicted what Ammel told a local court during his divorce proceedings. There, he said they didn’t have sex until January 2025. When confronted with the contradiction during his deposition last month, Ammel admitted to lying. He and his wife, Heather Ammel, weren’t divorced until November 2024, and Matthew said he didn’t want to admit that he had an affair with Sinema earlier that year.
“I lied during the first deposition because I was scared I was going to lose my children,” he said during his July 28 deposition. A judge awarded Heather custody of the kids anyways.
Meanwhile, an evidentiary hearing is set for Wednesday in Heather’s lawsuit against Sinema. Headline USA plans to cover that hearing.
