MyPillow CEO Mike Lindell shared details of an FBI search warrant for his cell phone despite being told not to "disclose the existence" of the subpoena.

Lindell, a Donald Trump supporter and one of the most prominent pushers of 2020 election misinformation, said his cell phone was seized by federal agents on Tuesday while he was at a Hardee's fast-food drive-thru in Mankato, Minnesota.

Lindell said he was questioned by the FBI about Tina Peters, a Colorado clerk who is under indictment over allegations of tampering with election voting equipment. Lindell said he was also asked about Dominion Voting Systems, and fellow 2020 election denier Doug Frank.

Speaking on his show The Lindell Report, the MyPillow CEO said he originally refused to hand over his phone and demanded to see a warrant from the federal agents.

Lindell said he then called his lawyer who advised him to hand over his phone.

During the show, Lindell shared a letter from the United States Attorney District of Colorado which he said accompanied the search warrant which states there is an official criminal investigation of a "suspected felony" in Colorado.

Last week, Peters, a Mesa County clerk who ran for the GOP nomination for Colorado secretary of state in June, pleaded not guilty to 10 felony and misdemeanor counts including tampering with election equipment and official misconduct.

The letter requested Lindell not to reveal details of the subpoena issued against him as it may be "detrimental to the investigation" around Peters, while not under any legal obligation to do so.

The letter concludes by stating that if Lindell believes he cannot comply with this request then he should notify Aaron Teitelbaum, assistant United States attorney, who signs off the letter.

"Well Mr. Aaron Teitelbaum, I hope you're watching because this is your notification that I'm telling the world about this garbage," Lindell said.

Lindell then shared the search warrant handed to him by federal agents on Tuesday, as well as attachments detailing what the FBI hoped to retrieve from the MyPillow CEO.

In a statement to Newsweek, FBI spokesperson Vikki Migoya said: "In keeping with Department of Justice standard practices, except on rare occasions, the FBI does not confirm or deny, or otherwise provide updates on specific investigations. This would include describing investigative steps we might or might not have taken, interviews we might or might not have conducted, and information we might or might not have learned.

"Without commenting on this specific matter, I can confirm that the FBI was at that location executing a search warrant authorized by a federal judge.

"Generally speaking, allegations of criminal conduct are reviewed by the FBI for their merit with consideration of any applicable federal laws, but such a review does not necessarily result in the opening of a full investigation.

"When warranted, we take any actions appropriate to the matter, such as seeking further information, referring the matter to a partner agency or referring our findings to the appropriate U.S. Attorney's Office."
