Over the weekend, Trumps attorneys sent letters to the Republican National Committee (RNC), the National Republican Senatorial Committee (NRSC), and the National Republican Congressional Committee (NRCC) saying he would have to give explicit permission for his name or likeness to be used in fundraising appeals.

The Trump brand has been a fundraising juggernaut for Republicans and the move to crack down on the GOPs top fundraising and messaging organs could hamstring the party as it seeks to win back the House and Senate in 2022.

Trump has stated publicly that his primary goal is to return Republicans to being a governing majority.

However, his actions suggest hes still furious at the 10 House Republicans and seven Senate Republicans that voted to impeach him, as well as with Senate Minority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellDemocrats near pressure point on nixing filibuster We need a voting rights workaroundBiden takes victory lap after Senate passes coronavirus relief packageMORE (R-Ky.) and other GOP leaders that have called on the party to move away from his brand of politics.

One Trump ally said the cease-and-desist was partly to retaliate against his critics, partly a power move to control the flow of money, and partly a business decision for a mogul who has made a fortune off licensing and business agreements.

Trump could also at some point seek a cut of the fundraising appeals that bear his name to direct additional cash toward his political war chest, which is already sitting at $35 million.

The McConnell tension definitely opened the floodgates, and in a lot of ways its about controlling the purse strings and exerting himself as the leader of the party by controlling the flow of money, the ally said. But its also about protecting his brand and maintaining exclusive control over his image.

Its unclear at the moment what the impact will be on GOP fundraising.

The RNC and NRSC were still using Trumps name in fundraising emails sent out over the weekend.

In a letter responding to Trumps attorney, RNC chief counsel Justin Riemer fired back, saying the GOP has every right to refer to public figures as it engages in core, First Amendment-protected political speech, and it will continue to do so in pursuit of these common goals.

The letter said that Trump had already personally approved the RNCs use of his name for fundraising, including for the upcoming donor retreat in Palm Beach, where Trump is expected to speak.

GOP operatives are wondering how far Trump will go to enforce the cease-and-desist.

Trump could still allow for his name to be used in some instances and its possible that the campaign arms will find loopholes that allow them to still raise money off the former president.

“We’re gonna have the resources we need to win the majority, I’m not worried about that,” Emmer told The Hill on Monday.

The Minnesota Republican said he hasn’t talked to Trump about it, but that he doesn’t believe Trump’s motive in restricting the use of his brand was retribution for the 10 GOP House members who opted to vote to impeach.

“You’ll have to ask him what he’s going to do, Emmer said. I mean, I saw his speech at CPAC and he’s going to continue to be involved. Let’s face it, he’ll be a force in this country and in the political landscape regardless. He was before he became president and I imagine he’s going to continue that way.

Trump’s brand is enormously helpful to Republicans when it comes to fundraising and generating enthusiasm among the base. Some Republicans are worried his latest move could be a drag on their efforts to win back majorities in the House and Senate.

Invoking Trump is an absolute winner when it comes to fundraising, said one Republican strategist. Its been really valuable in building a low-dollar fundraising organ for the party. Hopefully theyll get this worked out, because as it stands, its a huge and totally unnecessary hurdle to overcome.

Trumps GOP critics are fuming, saying its further evidence that Trumps only loyalty is to himself.

Republicans are once again being reminded about how theyre bowing down at the altar of someone who doesnt care about them, said Doug Heye, the former communications director at the RNC. Loyalty is not a two-way street with him. Hell cast you aside if he wants to. He doesnt feel that he needs the GOP right now and knows that if he wants them back, theyll come running, so theres no incentive for him to do anything else.

The fundraising dust-up comes as Trump ramps up his attacks on the Republicans that voted to impeach him.

Over the weekend, Trump vowed to travel to Alaska to try and oust Murkowski.

Murkowski is the only Senate Republican up for reelection in 2022 who voted to impeach Trump.

Republicans are confident that Murkowski, who lost a primary in 2010 but still won the general election in a write-in campaign, is safe. The state recently passed a ballot measure to implement an open primary in which the top four candidates from any party move on to the general election, all but ensuring Murkowski will get out of the primary.

Ballot Measure 2makes it hard to see where Trump campaigning against her would make any ultimate difference, said Art Hackney, a GOP strategist in Alaska. While she would be very vulnerable in a Republican primary, there are a broad swath of the resource community who she has earned the respect of. And with initial interest by groups like Club for Growth diminishing, and McConnell saying the committee will back her, and people like Senator Barrasso saying they will come and campaign for her it’s probably not enough to tip the scales against her.

Still, Trumps moves are a sign of his influence within the GOP and the ongoing struggle over the direction of the party that has played out since he left office.

Blunt was not among the most vocal Trump critics and he did not vote to impeach, but conservatives talked privately about him potentially attracting a primary challenger because they believed he could be replaced with a MAGA-style candidate.

Its clear the political atmosphere has become toxic and honestly the job of being a senator is a bad one, said Heye. Its a negative workplace. Members arent happy, and thats especially true if youre in minority and have to show fealty to a guy who could cross you at any moment.
