MyPillow CEO Mike Lindell shaved his signature mustache to crash the Democratic National Convention this week ― but he didn’t shed his baseless insistence that the 2020 election was rigged against Donald Trump.

The conspiracy-theorist bedding boss was filmed arguing with a 12-year-old content creator named Knowa in a pathetic attempt to re-sell his claptrap about balloting fraud.

“257,000 votes — this happened last week, a judge ruled in Georgia — that are missing from the 2020 election,” Lindell, also wearing a fedora and sunglasses, said in a clip shared Wednesday by the Meidas Touch Network. (Watch it below.)

“So your source is, ‘Trust me, bro’?” Knowa snapped back.

“No,” Lindell insisted. “It’s in your papers in Georgia. You need to read your news.”

Knowa punctuated his dismissal of Lindell’s shtick by telling the failed election-truther host, “You’re full of crap.”

Knowa shared a longer look of the exchange with the headline, “Mike Lindell is an idiot as expected.” Lindell gave a rambling account of how he “got to take off my tinfoil hat” to the smiling Knowa.

Earlier, Lindell reposted a clip from conservative platform Frank Speech after the removal of his 30-year-old facial hair. In the video he outlined his plans to infiltrate the convention and “find the media.”

His plan to crash the DNC had been in the the works for a while but didn’t make it any less ridiculous.

DNC Chair Jaime Harrison, who invited Knowa, was not amused. He warned Lindell on X, “The next time you feel compelled to yell at another young Black kid… come find me!”
