Bed Bath & Beyond has cut ties with My Pillow, the pillow manufacturing company founded by Trump supporter Mike Lindell, the retailer confirmed to Insider.

Lindell first reported the retailer axing his products,   telling a Fox News affiliate   and   right-wing media outlet RSBN   about stores dropping the brand. In the interviews, Lindell attributed the retailer's decision to social media pressure led by "leftist groups."

"They're trying to cancel companies now," he told RSBN.

Bed Bath & Beyond said it's getting rid of the pillow brand because it's not selling well.

"As previously announced, we have been rationalizing our assortment to discontinue a number of underperforming items and brands. This includes the My Pillow product line," a Bed Bath & Beyond spokesperson told Insider in an email. "Our decisions are data-driven, customer-inspired, and are delivering substantial growth in our key destination categories."

Bed Bath & Beyond was one of the largest national retailers stocking My Pillow products.

On RSBN, Lindell claimed that other retailers were also dropping the brand, including H-E-B and Kohl's. H-E-B did not respond to a request for comment.

Kohl's said in a statement to CNBC   in a statement that it will sell through its current inventory and not order additional product due to "decreased customer demand."

My Pillow did not respond to a request for comment from Insider.

Lindell has been a vocal proponent of the baseless claim that voting machines switched votes to secure President-elect Joe Biden's victory,   a theory that he may have taken to the president in person on Friday .

Voting technology company Dominion - whose machines are central to the conspiracy theory Lindell has been spreading -   threatened "imminent" legal action on January 8 , calling the claims "false and conspiratorial."

That legal threat came two days after protesters were   encouraged by Trump to march on the Capitol , in events that spiralled into a deadly riot.   Lindell has continued to support the president   following these events, offering a MyPillow discount code "FightForTrump" for customers ordering directly.
