Lindell, a mega-millionaire and staunch Trump loyalist, made the remarks Friday ahead of a hearing in a Washington court where he and pro-Trump attorneys Sidney Powell and Rudy Giuliani face a defamation lawsuit from Dominion Voting Systems due to their false claims about the companies alleged involvement with “stealing” the election for President Joe Biden. These extraordinary claims have already been thoroughly litigated and wholly debunked.

“Our country was attacked by China. The election was hacked and we’re gonna have a cyber-symposium,” Lindell vowed during a press conference outside a Washington federal court.

The MyPillow CEO said that his “cyber experts” would show “packet captures” that are “100 percent non-subjective evidence.”

“And we have all the packet captures for the whole election,” he claimed.

Lindell said that the August event would be attended by cyber experts, politicians and the media. The pro-Trump businessman argued that after the symposium, the Supreme Court would unanimously rule to throw out the election results—something that legal analysts have already pointed out is not possible.

“It’s gonna be 9-0. They’re gonna take this election down, and, yes, Donald Trump will be your president. He is your president now,” Lindell insisted. He went on to attack Dominion repeatedly in his remarks, despite the defamation case against him, which he had come to attend. “These criminals, they used this and committed one of the biggest crimes against humanity, were part of it, in history,” the businessman claimed of Dominion.

Dominion filed a $1.3 billion defamation lawsuit against Lindell in February. The voting systems company also filed suit against Powell and Giuliani, who led the charge in filing groundless election challenge lawsuits on behalf of Trump. Giuliani’s New York law license was suspended this week, after a court in the state determined that he had repeatedly made false and inaccurate statements about the 2020 election.

Dozens of election challenge lawsuits filed by Trump and his supporters failed in state and federal courts. Even judges appointed by the former president and other Republicans rejected the often bizarre allegations. Audits and recounts in key battleground states—including in areas where the election was overseen by pro-Trump Republicans—reaffirmed Biden’s victory.

Former U.S. Attorney General William Barr, who was widely viewed as one of Trump’s most loyal Cabinet members, said in December that there was “no evidence” to substantiate the claims of widespread fraud. Additionally, the Cybersecurity and Infrastructure Security Agency at the Department of Homeland Security described the 2020 election as the “most secure in American history.” The federal agency, which was led by a Trump appointee at the time, asserted that there was “no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised.”

Regardless, Trump, Lindell, Powell, Giuliani and other prominent conservatives continue to claim that the 2020 election was fraudulent. These baseless claims also appear to have resonated with Republican voters. Polls have shown that many believe that Biden is not the legitimate president. The results of an Ipsos/Reuters survey carried out in May showed that 53 percent of GOP voters believe Trump is the “true president,” while 56 percent believe the election was tainted by fraudulent voting.
