“What I’m talking about, Steve, is what I’ve been doing since 9 January,” Mr Lindell said on Mr Bannon’s WarRoom Pandemic podcast.
“All the evidence I have — everything is going to go before the Supreme Court and the election of 2020 is going bye-bye.”
And he added, without providing any evidence: “It was an attack by other countries, communism coming in.
“I don’t know what they’re going to do with that after they pull it down.”
As Mr Bannon tried to cut in, Mr Lindell claimed: “Donald Trump will be back in office in August.”
Mr Lindell was one of Mr Trump’s most vocal supporters after he lost the election to Joe Biden, and has been sued for $1.3bn by Dominion Voting Systems for wild allegations against the company.
He told Mr Bannon that he did not understand why the firm would not let people “look inside” their voting machines.
Mr Lindell even added that he would allow people to look inside his company’s pillows if it was being claimed they were stuffed with rocks.
“A five-year-old can figure out they’re hiding something,” he added, despite the legal action he is facing.
