Mike Lindell told Kimmel he still speaks with Trump once a month - most recently about Trump's border fears

• MyPillow CEO Mike Lindell told Jimmy Kimmel he spoke with Donald Trump about once a month.
• He said their last conversation was "a couple of weeks ago" and was about the US border.
• Lindell, a staunch Trump ally, has backed Trump's challenges to the integrity of the 2020 election.

MyPillow CEO Mike Lindell speaks with former President Donald Trump about once a month, he told Jimmy Kimmel on Wednesday night.

Lindell said he most recently spoke with Trump "a couple of weeks ago," with the subject being the US border.

Lindell, a major GOP donor, was a staunch ally during Trump's time in the White House and has repeatedly supported unsubstantiated claims that the 2020 presidential election was stolen from Trump.

He visited Trump at the White House more than once, including speaking at a COVID-19 briefing. He also met with Trump during Trump's final week in office, leading to viral photos of him carrying printed notes referring to "martial law."

Trump has said he may run again for president in 2024.

"I've talked to him once every ... maybe month or so, if I'm down there," Lindell said, without explaining where he meant.

Kimmel then asked Lindell when they last spoke.

"A couple of weeks ago I guess, when he said he was worried about what was going down at the border," Lindell said. "He said: 'I'm really worried about what's going on.'" He did not elaborate on what else specifically they discussed.

Tightening the border between the US and Mexico and clamping down on immigration were cornerstones of Trump's 2016 election campaign. During his time in office, he issued anti-immigration executive orders and tried to build a $15 billion border wall between the two countries, which people are now climbing over with $5 ladders.

Lindell told Kimmel that he first met Trump in August 2016 when he "didn't know anything about politics."

"I met this man who had problems, solutions, and he knew what they manifest to," he said.

Lindell said that after he met Trump he thought, "Wow, this guy could be the greatest president ever."

He said that when he returned to Minnesota, he told the press that they had met, which he said led to a huge public backlash. "I was attacked like you've never seen," he said.

Lindell added that he wasn't in contact with Rudy Giuliani, another close Trump ally, whose apartment was raided by federal investigators just hours before Lindell and Kimmel went live on the air. Giuliani, who used to be Trump's lawyer, has spread voter-fraud conspiracy theories similar to those spread by Lindell.

During Wednesday's show, Kimmel grilled Lindell on his voter-fraud conspiracy theories, MyPillow's $1.6 billion lawsuit against voting-technology company Dominion, and his new social-media site, Frank.
