Kyrsten Sinema Bonded Out Boyfriend Matthew Ammel After His Assault Arrest, Court Docs Show

Court documents show former Sen. Kyrsten Sinema paid bail for boyfriend Matthew Ammel, her ex-bodyguard, after his assault arrest.

Former U.S. Senator Kyrsten Sinema allegedly posted bond to release her boyfriend, Matthew Ammel, from jail following his arrest for assaulting a physician, according to court documents obtained by TMZ. Ammel had been involuntarily committed to a hospital before the arrest, according to the reporting. Sinema, 50, was deposed in July as part of related legal proceedings. During that deposition, she described the start of a romantic relationship with Ammel, who served as her bodyguard and was married at the time the relationship began, according to US Magazine citing People's coverage of the deposition. The legal situation involves both criminal proceedings stemming from Ammel's assault arrest and civil or family court proceedings that prompted Sinema's deposition. Sinema represented Arizona in the U.S. Senate from 2019 to 2025, leaving office after choosing not to seek re-election.

Bias & framing notes

TMZ focuses on the criminal arrest and bail angle, citing court documents, which lends that specific claim moderate credibility as a primary source. US Magazine relies on People's account of deposition testimony rather than independently reviewing it. Both outlets are tabloid-adjacent and neither has fully corroborated the other's specific claims. The deposition quotes attributed to Sinema are secondhand through at least one additional outlet. The overall picture is consistent across sources but verification depth is limited.
