• Mike Lindell claimed "antifa things" were attempting to infiltrate his 72-hour conference this week.
• Lindell also said he had been warned an attack might be launched on the venue to steal devices.
• A video of the venue's parking lot showed three people singing hymns in front of the event hall.

MyPillow CEO Mike Lindell claimed on the last day of his three-day conference in South Dakota that "antifa things" were attempting to infiltrate the event, but video showed only a handful of people singing hymns in the parking lot.

Lindell alluded to fears of an attack by antifa - an umbrella term for militant anti-fascist groups - on the conference venue in a video seen by Insider. He's been hosting a marathon 72-hour conference, dubbed a cyber symposium, from Tuesday to Thursday in an attempt to prove his conspiracy theories involving the 2020 US election.

"They'd stick, it's called some poison pill, in so that everybody's stuff would have been ruined so they take your computers or whatever it is," Lindell said in video from the event. "I didn't even understand it all. I go, 'What?' Is that antifa things or people that have infiltrated, they're telling me this morning."

One of the conference's attendees, retired Army Col. Phil Waldron, also took to the stage and warned of a "credible threat" at the symposium.

"We detected disruptors inside, trying to get people ejected, really radical folks outside trying to penetrate," Waldron said. "We've got folks exchanging badges in the parking lot, press badges specifically. We've identified those agitators and provocateurs by photo imagery."

"They're obviously trying to subdue the message that Mike's trying to get out," Waldron added. "So this is a typical insurrection-type activities. This is part of the color revolution."

The Salon reporter Zachary Petrizzo, however, posted a video he filmed in the parking lot outside the South Dakota event hall on Thursday morning. The video showed neither a crowd nor protesters - only three people dancing and singing hymns.

Lindell also said on Thursday morning that he had been attacked outside his hotel on Wednesday night.

"I'm OK," he said. "It hurts a little bit. I just want everyone to know all the evil that's out there."

The AP spoke with the Sioux Falls Police Department spokesman Sam Clemens, who told the news outlet that his officers had taken a report about an assault at a hotel near the conference. Clemens said the incident happened at 11:30 p.m. Wednesday but did not identify Lindell as being involved in the incident.

Lindell did not immediately respond to a request for comment from Insider.

In July, Lindell offered $5 million to anyone who attended the conference who could disprove his conspiracy theory that China stole last year's election for Joe Biden. He later rescinded the offer of the money.

Claims by Lindell involving the election-technology company Dominion Voting Systems prompted a $1.3 billion defamation suit against the MyPillow CEO. Lindell was seen rushing off the event stage Wednesday at about the same time when news broke that a judge allowed the suit to go ahead.

Lindell attempted to have the defamation lawsuit dismissed during a hearing in June. The federal judge also ruled Wednesday that lawsuits by Dominion against the pro-Trump lawyers Sidney Powell and Rudy Giuliani could proceed.
