The “Cyber Crisis: Saving Tina Peters” event was aimed at rallying support for the former clerk of Mesa County, Colo., who faces charges accusing her of tampering with election equipment three years ago. Peters has pleaded not guilty, and her case goes to trial next week.

Byrne called out law enforcement and prosecutors during the forum, saying they would face violence if they did not drop the case.

“If you have any brains at all, which I’m not sure they do, they should be throwing in the towel and just surrendering and dropping this case against Tina because those who don’t are going to end up facing a piano wire and a blowtorch before this is over if I have anything to do with it,” Byrne said. “So I know that’s probably another felony, but f— it — threatening them like that — but there we are.”

Byrne, who said he was participating in the event from Azerbaijan, accused law enforcement of committing treason and claimed he had been hacking Venezuela’s government for two years.

“I don’t care how many felonies I’ve committed, and I don’t care that I’m committing felonies by threatening you,” he said of law enforcement. “You folks do your job or when this is over, the folks who are part of this are going to be facing, you know, piano wire and blowtorches before this is over. So you start doing your job and stop worrying about me.”

Byrne said Friday that his comments were “obviously a metaphor.”

“Please be aware that my turns of phrase like that are metaphoric expressions,” he said by text message. “There’s been no one more committed to peaceful resolution of this than I.”

He said his views on peace do not extend to people like former ambassador Manuel Rocha, who pleaded guilty this year to serving as a secret agent for Cuba for decades. “The only exception to peaceful resolution will be for any who turn out of Cuba and Venezuela, such as ambassador Rocha,” Byrne said by text message.

Byrne noted it was 4 a.m. in Azerbaijan when he participated in the event on X, and he may not have spoken as carefully as he otherwise would.

Spokespeople for the Colorado attorney general’s office and Mesa County district attorney’s office did not immediately comment Friday.

Byrne’s comments come three-and-a-half months ahead of the presidential election, as scholars, law enforcement agencies and election administrators raise alarms about the risk of political violence. Election officials have faced an onslaught of threats and harassment since the 2020 election and the Jan. 6, 2021, attack on the U.S. Capitol by a mob chanting about Donald Trump’s false election claims.

Two weeks ago, Trump was injured during an assassination attempt that left one of his supporters dead at a rally in Butler, Pa. The violence fueled new warnings of the risk to public officials and ordinary Americans, regardless of their political views.

Before today’s combustible political environment, the phrases Byrne used might have prompted outreach by authorities to advise against using such language, said Paul Charlton, a former U.S. attorney under President George W. Bush. These days, state and federal officials tend to take such talk more seriously. Byrne’s language, he said, “sounds not only like a threat but a confession and an acknowledgment that it could be a felony to make such a threat.”

Words alone can be sufficient to prosecute threats against public officials if authorities can show proof of intent to do harm, he said.

“That is an instance in which, in my mind, it is very much worth law enforcement’s attention,” Charlton said.

Byrne’s repeated references to the Peters trial — and the prosecutors involved in it — are important aspects of his overall comments, said Carol Lam, a former U.S. attorney for the Southern District of California who was also appointed by Bush.

“Because he references a specific trial and he’s talking about the people who are bringing the case, that should be very troubling to law enforcement,” she said. Even if he said he was speaking metaphorically, she added, “What does that matter if someone went out and bought piano wire at his suggestion?”

Two hours after The Washington Post contacted Byrne, he posted a statement on X that reiterated what he told a reporter about meaning his comments metaphorically. He said he wanted people to remain peaceful, but added information would come out that would “test our ability to remain peaceful and my ability to contribute to that cause.”

Byrne used this week’s online forum to argue for dropping the charges against Peters, who is accused of participating in a scheme to allow a purported data expert to secretly copy files from Dominion Voting Systems equipment in 2021. She faces seven felonies and three misdemeanors in a case that is scheduled to go to trial on Wednesday.

He has long championed Peters and others who have questioned the results of the 2020 election. Four days after members of the electoral college voted to give Biden a victory in December 2020, Byrne joined other Trump allies in the Oval Office to argue Trump could use the National Guard to seize voting machines. Also in the meeting were Trump-aligned attorneys Sidney Powell and Rudy Giuliani and former national security adviser Michael Flynn.

In the years since, Byrne has used his fortune and his nonprofit America Project to bankroll efforts meant to uncover problems with how elections are run, including a partisan review of the 2020 election in Arizona. Byrne and the America Project have helped fund groups like We the People Ariz. Alliance, an Arizona-based political action committee whose co-founder in March said she would “lynch” a Republican official who helps oversee elections in the state’s largest county. She later said her comment was a joke.

Courts and independent agencies have found no evidence of widespread election fraud.

Byrne led Overstock for two decades. He resigned in 2019 after it came to light that he had been romantically involved with Maria Butina, a Russian gun activist who pleaded guilty in 2018 to conspiring with a Russian official to infiltrate conservative politics in the United States. She was deported after serving a 15-month prison sentence. Byrne published a memoir this year that included a preface by Butina.

Dominion, the voting machine company, filed a $1.6 billion defamation lawsuit against Byrne in 2021. The case is ongoing. Dominion won settlements of $787.5 million with Fox News and $243 million with Newsmax and is seeking $1 billion or more from Giuliani, Powell and MyPillow CEO Mike Lindell.
