Lindell, an ally of former President Donald Trump, said he'd officially declare his bid at 11 a.m. ET on his website FrankSpeech.com.

"We've got to save our country. We can't have the RNC out there if they can't change," Lindell said during an interview on his web program, "The Lindell Report."

"I've said it before, they need to change what they're doing based on the current footprint in the country. You need a different input to get a different output."

Lindell's proposition comes after Ronna McDaniel, the RNC chair since 2017, signaled her intention to seek to lead the party for a fourth term.

"Guys, if you support me running against Ronna McDaniel, please email me," Lindell said in an earlier interview. He said he wants to hear all feedback, including negative.

"I'll step into that if God willing," he added.
