In the fall of 2022, Phoebe Petrovic, an investigative reporter at Wisconsin Watch and a member of ProPublica’s Local Reporting Network, noticed a pastor and his church appearing in local news coverage for their anti-LGBTQ+ protests . Looking closer revealed Pastor Matthew Trewhella’s startling history. And digging even deeper, she noticed an untold story: his broader influence on modern Republican politics . His rise helps illustrate the growing power of the Christian right in the Republican party. Here, Petrovic describes how she reported the story and what she learned.

What were the key takeaways from your reporting?

• A few decades ago, Trewhella was known as a militant anti-abortion activist. Today, he’s got a different reputation: thought leader on the far right, increasingly welcomed by Republicans.
• Trewhella helped to rehabilitate his reputation through his 2013 self-published book, “The Doctrine of the Lesser Magistrates,” which uses a 16th-century Protestant doctrine to argue that government officials have a God-given right and duty to defy laws, policies or court opinions deemed “unjust or immoral” under “the law of God.”
• He’s preached this doctrine to county Republican parties and local groups across the country, even to the National Sheriffs’ Association, a preeminent law enforcement organization.
• His book has influenced Second Amendment sanctuary resolutions. At least 10 measures across the country refer to lesser magistrates. One of the earliest, issued in 2019, was authored by a county commissioner who has described reading Trewhella’s book as a “turning point” for him.
• A prominent booster of debunked election conspiracy claims is using Trewhella’s book to disrupt future elections.

How does Trewhella fit into the election? What does he say about his work?

• In the cast of characters who might influence the upcoming election, Trewhella is not rallying crowds the same way as Steve Bannon, the former Donald Trump strategist, or Charlie Kirk, the founder of the conservative student group Turning Point USA. Trewhella is more behind the scenes, providing a religious justification for some far-right policies and causes.
• Trewhella says that he promotes nonviolence. But after an activist killed an abortion provider in 1993, he signed a document describing the murder of these doctors as “justifiable.”
• In a brief interview, I asked Trewhella about his reputational shift over the decades. He responded: “Most people will always only care about three things in life: me, myself and I. … It’s only because of their mundane, self-absorbed lives that they would think someone like me is an extremist. That’s my answer.”
• Trewhella did not respond to over a dozen attempts to set up a second interview. He did not answer written questions by email and refused a certified letter containing them.

What did experts tell you about Trewhella?

• Frederick Clarkson, a senior research analyst at Political Research Associates, which studies threats to democracy and human rights, has tracked Trewhella for decades. Clarkson said, “All of those county commissioners and mayors and whatnot who are entertaining this stuff, they’re putting people’s lives and the entirety of civil order at risk by playing footsie with Matt Trewhella.”
• Another extremism researcher, Devin Burghart, said, “I think that the public needs to know that he’s a dangerous theocrat, who would fundamentally alter the United States in irreparable ways that would harm many, including women, people of color and the LGBTQ community.” Burghart is president of the Institute for Research and Education on Human Rights, which tracks the far right.

What are some details that didn’t make it into the story?

• Trewhella has given sermons about violence, saying that pacifism is “heresy” and that “violence is a tool.” After the Jan. 6, 2021, attack on the U.S. Capitol, he gave a sermon titled “A Gathering of Patriots” in which he said, “Tyrants must be confronted with force or violence at times because that is the only way to defeat them and to cause their harm and their injustice to others to stop.”
• Timothy Bachleitner, a member of Trewhella’s church, is the chair of the Republican Party of Fond du Lac County. Reached by phone, Bachleitner said he received Trewhella’s blessing before seeking the position and that he has brought the doctrine of the lesser magistrates into his role.
• Trewhella is focused on counties. He organized a conference called “County before Country” with the goal of “expanding God’s Kingdom through Christian localism.”

This story took a lot of research. What else do you want to share about this subject?

Some Republican operatives in Wisconsin questioned why we were doing this story. They said Trewhella was old news from the ’90s. That’s not what our reporting showed. We found him cited by county commissioners, state lawmakers and former Trump administration officials, all in the past several years. In my home state of Wisconsin, the Republican Party of Waukesha County, the heart of the state’s Republican politics, has invited Trewhella to speak twice and promotes his teachings and book on its website, although its leaders downplayed the link when asked for comment.

“I just can’t imagine that they’d support this person,” said Bill Kruziki, a Republican former sheriff in Waukesha County, Wisconsin. “You can quote me on this: I think it’s a shame they do that.”

The reporting process itself was one of the most interesting I’ve had. One of my first steps entailed sending records requests to local officials who served in areas where Trewhella had given presentations. Within days, Trewhella had obtained a copy of the request and shared it on his social media profile and email newsletter, writing, “The wicked are trembling!”

And in the final stages of the reporting, I requested an interview with Republican Oklahoma state Sen. Dusty Deevers, who cited Trewhella when defending his calls to ignore federal law that violated “God’s word.” An aide denied my request and included in his email “a brief gospel exhortation,” urging me and my readers “to turn from sin, run to Christ, trust Him, and enjoy fellowship with him forever.”
