Trump-Endorsed 'America's Sheriff' Projected To Win Arizona GOP Primary Amid Sex-And-Abuse Allegations

Mark Lamb, the former Pinal County sheriff who built a national profile as a reality-TV lawman calling himself "America's Sheriff," is projected to win the Republican primary in Arizona's 5th Congressional District despite explosive allegations that surfaced late in the race.

Allegations Reported By The Arizona Republic

Reporting in the Arizona Republic detailed allegations that, over several years, Lamb exchanged sexually explicit messages and photos with multiple women and engaged in real-life affairs. The stories also say Lamb allegedly intimidated at least two people who spoke publicly about the encounters — including threats to use Arizona's laws governing nonconsensual distribution of intimate images (commonly described as "revenge porn") or otherwise subject accusers to "collateral damage."

What The Records And Officials Say

The Pinal County attorney's office subsequently concluded that Lamb appeared to receive "a different standard of review" when misconduct complaints involving him were made, and that some requests to open investigations he initiated were not formally documented, according to the reporting. Campaign lawyers for Lamb told the Arizona Republic the allegations were "baseless and harmful," but did not rebut each specific claim in the public reporting.

Accounts From People Named In The Reporting

One woman, Jillian Stannard, said Lamb involved her then-husband in an exchange that included Lamb's wife and others sending sexually explicit photos and engaging in occasional sexual favors; Stannard told the paper she was later threatened after reporting the situation to leaders of the Church of Jesus Christ of Latter-day Saints. Another woman named in the coverage, Tammy Peacock — who died in 2021 — had publicly claimed an affair with Lamb and said he threatened a revenge-porn investigation after she posted about it.

Political Reaction And Local Dynamics

Allies of conservative groups reportedly moved to limit discussion of the allegations at a local Republican meeting, and other reporting says Lamb used a racist joke in a private exchange with a border vigilante. The county attorney named in some workplace complaints has denied wrongdoing.

Campaign Status And Context

Arizona's 5th Congressional District is strongly Republican, making Lamb the presumptive favorite for the November general election if his nomination is certified. The seat is open because Rep. Andy Biggs is pursuing a different office. Lamb conducted parts of his campaign from a reported $3 million ranch in Tennessee where his family resides.

Background: Law Enforcement To Media Personality

Famous for cultivating a media-forward image, Lamb served as Pinal County sheriff from 2017 through 2024. He has appeared on numerous episodes of Live PD, invited A&E cameras into his county jail, launched a streaming outlet called "American Sheriff," and earned the nickname "Sheriff Hollywood" from some colleagues. He launched a short-lived 2024 U.S. Senate campaign, losing in the Republican primary to Kari Lake, who then lost the general election to Democrat Ruben Gallego.

Politically, Lamb aligns with a Trump-era Republican profile: he has expressed hard-line views on immigration and promoted election-related skepticism. Extremism researchers have noted his connections to the so-called "Constitutional Sheriff" movement, a right-leaning current that emphasizes county sheriffs' powers.

What Comes Next

The allegations remain contested and, to date, have not resulted in criminal charges reported publicly against Lamb. Voters in the 5th District will move on to the general election in November, when the projected Republican nominee will face the Democratic contender. The controversy has added scrutiny to what otherwise would be a routine GOP hold in a heavily Republican district.
