Kyrsten Sinema Drops Affair Bombshell Under Oath

Former U.S. Sen. Kyrsten Sinema made a series of startling admissions under oath about an intimate relationship with her married security guard. The revelations emerged in federal court filings tied to a lawsuit filed by the guard’s ex-wife.

Sinema, who was elected as a Democrat before becoming an independent, testified during a July 31 deposition in a case brought by Heather Ammel. Ammel is suing under North Carolina’s alienation-of-affection law, claiming Sinema helped destroy her 14-year marriage to Matthew Ammel.

Sinema described the first encounter around Memorial Day 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,” she said.

She testified that the relationship continued in New York City the following month, then again at her Washington, D.C., apartment after a red-eye flight, and later during a fundraising trip to Aspen, Colorado. Another encounter occurred at her home in Phoenix in October 2024.

Sinema acknowledged she knew Ammel was married and had three children throughout the relationship. When questioned about a message that read, “Putting my hand on your heart. I’ll see you soon. I miss you,” a lawyer asked whether a wife might be concerned. “Yes,” Sinema replied.

Heather Ammel discovered the affair after her husband returned home intoxicated. She described Sinema as “insidious” and “a woman who is willing to break up a family.” The couple separated in November 2024 and finalized their divorce in March 2026.

Sinema’s legal team has sought to dismiss the case on jurisdictional grounds. An evidentiary hearing was scheduled for August 19. The former senator left office in early 2025 after choosing not to seek another term. The legal battle continues as more details surface from the depositions.
