Excepts from the NY Times story:

A chief sponsor of many rallies leading up to the riot, including the one featuring the president on Jan. 6, was Women for America First, a conservative nonprofit. Its leaders include Amy Kremer, who rose to prominence in the Tea Party movement, and her daughter, Kylie Jane Kremer, 30. She started a “Stop the Steal” Facebook page on Nov. 4. More than 320,000 people signed up in less than a day, but the platform promptly shut it down for fears of inciting violence. The group has denied any violent intent.

By far the most visible financial backer of Women for America First’s efforts was Mike Lindell, a founder of the MyPillow bedding company, identified on a now-defunct website as one of the “generous sponsors” of a bus tour promoting Mr. Trump's attempt to overturn the election. In addition, he was an important supporter of Right Side Broadcasting, an obscure pro-Trump television network that provided blanket coverage of Trump rallies after the vote, and a podcast run by the former Trump adviser Stephen K. Bannon that also sponsored the bus tour.

“I put everything I had into the last three weeks, financial and everything,” Mr. Lindell said in a mid-December television interview.
