Denver Riggleman

In December 2016, Riggleman filed papers to seek the Republican nomination for governor of Virginia in the 2017 gubernatorial election. His opponents in the Republican primary were former President George W. Bush counselor and Republican National Committee chairman Ed Gillespie, Prince William County Board of Supervisors chairman Corey Stewart, and state Senator Frank Wagner of Virginia Beach.[5] Riggleman suspended his campaign on March 16, 2017.[4]

Riggleman had expressed interest in running for Governor in 2021 as an independent or third-party candidate, citing his belief that the Republican Party of Virginia is broken.[10]

In the 2018 elections, Riggleman was the Republican nominee for the United States House of Representatives election for Virginia's 5th congressional district. He defeated Cynthia Dunbar, who had lost the Republican nomination in the 6th district just weeks before, in the final round of voting to win the nomination.[11] The Republican incumbent, Tom Garrett, did not run for reelection.[12]

In the November 2018 general election, Riggleman defeated Democratic nominee Leslie Cockburn with 53% of the vote to Cockburn's 47%.[13]

During the campaign, Cockburn accused Riggleman of being a "devotee of Bigfoot erotica", based on an image he shared from his Instagram to promote a book titled The Mating Habits of Bigfoot and Why Women Want Him. In an interview with CRTV Riggleman said the image was an obvious joke, but that he had an interest in Bigfoot, and co-authored the actual self-published book Bigfoot Exterminators, Inc.: The Partially Cautionary, Mostly True Tale of Monster Hunt 2006, with ESPN writer Don Barone.[14] In a phone interview with The Washington Post, he clarified that it was an "anthropological book sort of based on parody and satire" and said, "I thought it was funny. There is no way that anybody's dumb enough to think this is real."[15]

In 2020, Riggleman released a book titled Bigfoot… It's Complicated, and described himself as a "Bigfoot scholar." Despite that, he does not believe in the creature's existence.[16]

Riggleman is the only member of the Republican party to speak on the House of Representatives floor against QAnon.[17] He is a co-sponsor of 2020 US House resolution H. Res 1154 "Condemning QAnon and rejecting the conspiracy theories it promotes".[18] He is also one of the co-authors of the Network Contagion Research Institute (affiliated with Rutgers University) report called "THE QANON CONSPIRACY: Destroying Families, Dividing Communities, Undermining Democracy"[17] which he wrote before the January 6, 2021 storming of the US Capitol. "When ideas or fantasy are weaponized, there is a metamorphosis from harmless, bizarre theories to a dangerous bloom of tribalism and dehumanization of others," he wrote in the report. "This bloom expands digitally from person to person, absorbing and then converting a tribe that believes alternate realities based on a directed stream of algorithmically and group targeted data, ignorant analytic white papers, memes, ideas and coded language."

Since leaving Congress in January 2021, Riggleman has been working with experts and academics at the Network Contagion Research Institute to study disinformation and how to combat it.[19]

The Rappahannock County Republican Party criticized Riggleman after he officiated a same-sex wedding between two of his friends, and in September he was censured by party officials who claimed that he had "abandoned party principles" over fiscal and immigration policy.[20]

On September 26, 2019, Campbell County Supervisor Bob Good—who also worked as an athletics official at Liberty University—announced his intention to challenge Riggleman in the 2020 Republican primary. In his announcement, Good accused Riggleman of "betraying" the trust of conservative voters in the 5th district along with casting votes that were not in his constituency's best interest. Riggleman secured key endorsements on the right, including from Liberty University President Jerry Falwell, Jr.[21]

The local party leaders of the 5th Congressional District Republican Committee chose to determine the 2020 nominee for the fifth district by a convention instead of a primary election.[22] On June 13, 2020, Good defeated Riggleman at the nominating convention[23] with 58% of the vote to Riggleman's 42%.[24]

On December 11, 2020, Riggleman gave a farewell address on the floor of the House. He said his experience as an Air Force intelligence officer taught him "... the invaluable lesson of considering the source" when examining disinformation. He stated that "a well-instructed" and knowledgeable people are the pillars of a functional republic, and that "Those pillars are now being assaulted by disinformation and outlandish theories surrounding this presidential election." Riggleman added "As we transition to a new administration I implore all to consider the sources of information you receive, to fact check diligently", he pleaded, asking his fellow Americans "to recognize that many bad actors who spread spurious and fantastical conspiracy theories under banners like QAnon, Kraken, 'Stop the Steal, 'Scamdemic' and many other emotive terms and coded language are not disseminating information rooted in knowledge but with questionable motives and greed. They are rooted in misunderstanding, or fraud or in some cases, ignorance." He told "all those on the end of the disinformation fire hose" that "unbiased, fact-based information sustains our republic," adding that "disinformation hinders our free exchange of ideas and creates super spreader digital viruses that create a fever of nonsense." He asked his audience to remember that "people are more important than party" and that "pandering is a political sickness."[25]
