The White House is actively weighing whether to pull President Donald Trump's endorsement of Pinal County Sheriff Mark Lamb, the Republican candidate for an Arizona congressional seat now engulfed in allegations of extramarital affairs and sexual misconduct, a White House adviser told the Daily Caller.
The adviser, who works closely with the White House on endorsement decisions, said the move is "definitely on the table", language that signals the president's team views the Lamb situation as a serious liability heading into what should be a safe GOP pickup.
Trump gave Lamb his "complete and total endorsement" in November, calling the sheriff a "MAGA warrior" on Truth Social and declaring, "HE WILL NEVER LET YOU DOWN!" That praise now looks premature. The Arizona Republic published a report Wednesday detailing allegations that Lamb and his wife, Janel Lamb, engaged in "swinging", partner swapping and extramarital affairs, over a period of years. The report drew on social media posts, Facebook chats, and photographs shared by women who say they were directly involved or harmed.
Jillian Stannard, the former wife of an employee in Lamb's sheriff's office, alleged that her spouse admitted Lamb had facilitated a yearslong sexual affair between the employee and Janel Lamb. Stannard shared Facebook chats and photos with the Arizona Republic and took to social media to air the claims publicly.
A second woman, Tammy Peacock, made separate allegations before her death in 2021. Peacock claimed she had an affair with Lamb and that the sheriff threatened her after she said she would share communications documenting the relationship. She posted a video she claimed showed a photo of herself and Lamb having sex. Explicit messages attributed to exchanges between Peacock and Lamb were also cited, including sexually graphic language.
Peacock was found dead in 2021. A medical examiner reported her blood tested positive for methamphetamine. No criminal charges related to her death have been filed against anyone.
Former Pinal County Attorney Kent Volkmer said his office had been directed to "explore" criminal harassment charges against the women making allegations, not against Lamb himself. Volkmer conducted what he described as an informal investigation and determined the man in one photo was not Lamb, though he acknowledged he did not examine the photo's origin. He also explored Peacock's criminal record and what he called past abnormal behaviors.
Volkmer's own assessment of the underlying claims was far from a clean bill of health for the sheriff:
"I think I want it to be bulls***. But I'm not going to tell you that it is bulls***. I don't know."
Volkmer added that a formal investigation would have been a conflict of interest, given his professional relationship with Lamb's office. No criminal charges have been brought against Lamb in connection with any of the allegations.
The unnamed adviser framed the deliberation in blunt political terms. Trump treats his endorsement as a "gold standard," the adviser said, and the White House has "taken great lengths to protect its worth." The Lamb situation now threatens to repeat a pattern the president's team has already lived through once this cycle.
"So far, the only federal candidate who had the president's endorsement and lost this cycle was Tony Gonzales following the revelations of his sexual abuse scandal, so they're very sensitive to the same thing happening with Mark Lamb, who is facing similar accusations."
The Gonzales episode cost Republicans a seat and handed Democrats a talking point about GOP vetting failures. For a White House that has made endorsement discipline a signature of its political operation, a second scandal-driven loss in the same cycle would be a self-inflicted wound.
The adviser noted the White House already has an alternative in mind. Daniel Keenan, another Republican running for the same Arizona seat, was described as "closely aligned with the president and his agenda."
"They've pulled endorsements before, and they have a strong alternative candidate in the race, Daniel Keenan, who is closely aligned with the president and his agenda."
Former NFL kicker Jay Feely is also running for the seat, though the adviser indicated Trump has expressed a preference that Feely run in a different district or for a different office.
Trump has shown a willingness to cut ties with Republican candidates and officeholders who cross him or become political liabilities. He recently pulled his support from Rep. Jeff Hurd after a House vote on tariff authority, demonstrating that the endorsement is not a lifetime guarantee.
The broader question for the GOP is whether the party's vetting process catches these problems before the endorsement goes out, or only after the damage is done. The Lamb allegations did not surface overnight. Multiple women had aired claims on social media. The LDS Church conducted its own inquiry into claims lodged against Lamb. Volkmer's office had explored harassment charges against the accusers. All of this preceded the Arizona Republic's Wednesday report.
The fallout from misconduct scandals within Republican ranks has already prompted legislative responses. Rep. Lauren Boebert has pushed to revoke congressional pensions for members who resigned under misconduct clouds, signaling that the party's base expects real consequences, not quiet exits.
And Lamb is not the only Republican to face serious personal allegations in recent months. Rep. Max Miller's own lawyers conceded he fabricated witness claims in a domestic violence case, adding to a pattern that has tested voters' patience with candidates who campaign on law and order while their personal conduct tells a different story.
The Daily Caller reported that both the White House and Lamb's campaign had not responded to requests for comment as of publication. Lamb himself has not been directly quoted addressing the specific allegations in the reporting.
That silence may not last. If the White House does pull the endorsement, it will be a public rebuke from the most powerful figure in Republican politics, and a signal that no candidate, however aligned with the MAGA agenda, gets a pass when personal conduct threatens the party's credibility.
The Arizona race now sits in limbo. Lamb remains the endorsed candidate. The allegations remain unresolved. And the White House, by its own account, is watching closely.
Several questions remain unanswered. No formal charges have been filed against Lamb. The LDS Church inquiry's conclusions, if any, have not been made public. The full scope of the social media posts and communications cited in the Arizona Republic's reporting has not been independently verified. And neither Lamb nor his campaign has offered a public defense.
For voters in the Arizona district, the situation boils down to a simple test: Does the candidate meet the standard the president himself set when he called Lamb a warrior who would "never let you down"?
The White House, at least, appears to have its doubts. And in Trump's political world, doubt is usually the last stop before the door.
A presidential endorsement should mean something. If the facts bear out, pulling this one isn't just smart politics, it's the bare minimum.
