'No More Money For RINOs': How Trump's Fight With The GOP Is All About Control

The latest Trump-versus-The-Establishment skirmish is over one of the things couples fight about most.

Money.

"No more money for RINOS," former President Donald Trump said in a statement Monday night, using the acronym for "Republicans In Name Only," which is what conservatives call Republicans they deem not sufficiently conservative. "They do nothing but hurt the Republican Party and our great voting base—they will never lead us to Greatness. Send your donation to Save America PAC at DonaldJTrump.com. We will bring it all back stronger than ever before!"

Trump's appeal follows a similar one he made last month at the Conservative Political Action Conference, when he said, "There's only one way to contribute to our efforts."

And that Monday one came after a lawyer for his political action committee on Friday sent a "cease-and-desist" letter to the Republican National Committee, and to other party committees tasked with electing Republicans to the House and Senate, demanding they stop using the former president's name and likeness to raise funds. Politico first reported news of the letter.

RNC lawyers wrote back, saying the organization has "every right" to use a public figure's likeness. NPR was able to view the contents of the letter. It notes RNC Chair Ronna McDaniel's "close relationship" to Trump and that she moved quickly to quash the beef, reaching out to the former president this weekend.

"I'm not a lawyer, but I would assume stopping the RNC from using his image/name is totally unenforceable since he's a public person," Alex Conant, who was an RNC press secretary and worked on the presidential campaigns of former Minnesota Gov. Tim Pawlenty and Florida Sen. Marco Rubio, told NPR.
