Donald Trump and the RNC have publicly reached a detente

But one Trump supporter thinks the RNC is secretly trying to undermine the real estate mogul

(CNN) —  

The Republican National Committee is running a secret war room to take out Donald Trump’s presidential campaign.

Or so says Roger Stone, the former Trump political adviser, who still supports Trump.

Stone told CNN that he’s absolutely convinced the Republican Party is trying to knock the celebrity billionaire out of the race because he’s not the candidate of the establishment elite.

“I talk to a lot of reporters on a background, and sometimes off the record, basis. Sometimes, when I say to them, ‘Where did you get this hit piece of information on Trump?’ They’ll tell me, ‘Oh, a source at the Republican National Committee.’ Come on. This is the game. It’s the way it works,” Stone told CNN’s John Berman Wednesday.

Stone even predicted that RNC Chairman Reince Preibus “will deny this if anybody even bothers to ask him about it.”

Well, we bothered. And at least on that point, Stone was right on. The RNC dismissed Stone’s allegation as a conspiracy theory.

“It’s located at Area 51. Elvis runs it,” RNC spokeswoman Allison Moore told CNN, tongue firmly planted in cheek.

We asked Stone for some evidence to prove his claim. He didn’t offer any up.

After some initial tensions, Trump and party officials have struck a public détente. Both Trump and Priebus have recently been complimentary of each other. And Trump has said he thinks the RNC is treating him fairly – at least right now.
