CNBC and others begin the process of following the money:

The rally, officially known as the “March to Save America,” was largely organized by a 501(c)(4) group known as Women for America First. The organization was certified by the Internal Revenue Service as a nonprofit that can engage in limited political activities. These groups are known as dark money organizations as they do not publicly disclose their donors.

However, America First Polices, a pro-Trump policy advocacy dark money group, did disclose in 2019 that they contributed to Women for America First. America First’s 990 disclosure form from that year shows they contributed $25,000 to Women for America First.

America First Policies, which is also a 501(c)(4) that does not disclose its donors, is chaired by Linda McMahon, a longtime Trump ally and former head of the Small Business Administration. The 2019 filing shows America First Policies ended up raising over $30 million. They were not involved with the planning of the rally itself.

Women for America First is chaired by Amy Kremer, a longtime political operative that was once the head of the Tea Party Express, an organization that was created to support the conservative Tea Party movement. Kylie Jane Kremer, the executive director of Women for Trump, is named on the rally’s permit as the person in charge. The permit was first obtained by The Washingtonian.
