Former U.S. Senator-turned-lobbyist Kyrsten Sinema is facing a lawsuit alleging an affair with her formerly married bodyguard, Matthew “Matt” Ammel.
Ammel’s ex-wife filed the lawsuit against Sinema based on North Carolina’s “homewrecker law” back in September with a superior court in North Carolina. The lawsuit became public after the case was moved to the District Court for the Middle District of North Carolina.
The Ammels were married for 14 years and had three children together prior to their separation in November 2024.
Ammel joined Sinema’s security detail in early 2022. The lawsuit alleged that the adulterous relationship between Sinema and Ammel began at some point between late 2023 and early 2024.
The lawsuit also accused Sinema of giving gifts to Ammel, including psychedelic treatment. Sinema was further accused of directing Ammel to bring MDMA drugs, which are illegal, on a work trip so she could guide Ammel through a psychedelic experience.
During Sinema’s last year in the Senate while their alleged affair was well underway, Sinema allegedly hired Ammel to her staff as a Defense and National Security Fellow in addition to his security guard duties.
The two were alleged to have attended multiple concerts together: U2, Taylor Swift, Green Day, were among those listed.
The lawsuit claims Sinema’s former head of security allegedly even warned Ammel about Sinema having affairs with other security members upon her resignation in the fall of 2023.
During those last two years when Ammel was on board, Sinema’s security expenditures outpaced those by her colleagues and presidential candidates: over $1.7 million.
Sinema continued spending campaign funds into summer 2025. Expenditures amounted to over $390,000 over the course of three months; much of it went to similar expenses alleged in the lawsuit: private security and jet-setting.
One unusual expenditure noted by media reports involved several hundred dollars given to a middle school PTO in North Carolina. It appears that payment may have been in connection to Sinema’s alleged affair and Ammel’s children.
Ammel, an Army veteran, served over 17 years as a paratrooper and Green Beret before leaving the service in 2020.
Last February, Sinema had Ammel testify before the House Appropriations Committee in favor of ibogaine research as part of her lobbying effort for funding psychedelic clinical studies. Ibogaine is a psychoactive compound derived from an African shrub, the iboga tree. It is not currently legal in the country and does not have FDA approval. Certain clinics within the country do use ibogaine for treatments.
After growing closer with Sinema, Ammel was appointed to a fellowship within the Office of University Affairs at Arizona State University.
Last September, Ammel was a guest speaker at the screening of a 2024 Netflix documentary about Navy SEALs treating mental illness with psychedelics, “In Waves and War.” Ammel was presented as a North Carolina Special Operations Veteran and Ibogaine VETS Grant Recipient.
It appears the psychedelic treatments weren’t having their desired effect.
Ammel was arrested in November for assaulting an officer while at a hospital in North Carolina.
Ammel was placed on psychiatric hold for allegedly strangling a medic, per documents discovered by Fox 10 Phoenix.
