From this NYT story, which was also linked to below:

The jockeying comes as the party struggles to chart its path forward after losing the House, the Senate and the White House during Mr. Trump’s tenure, with moderate party leaders pushing the party to move beyond the divisive former president while much of the G.O.P. base remains firmly behind him. Who controls a majority of donors’ cash is set to be a fiercely contested point of dispute as Republicans try to regroup and take back power in the 2022 midterm elections.

What’s more, Mr. Trump’s advisers believe the future of party fund-raising is in low-dollar contributions, not the class of major donors who have mostly signaled that they want distance from him after his months long push falsely claiming that the Nov. 3 election had been stolen, which led to the Jan. 6 riot at the Capitol.
