Donald Trump’s campaign strategist Roger Stone — embroiled with his boss in a “you can’t fire me/I quit” hissy fit — says he resigned in part because of Trump’s “diversion to food fight” with Megyn Kelly “away from core issue messages.” After the Washington Post broke the news Saturday morning that Trump had fired Stone, Stone tweeted “Sorry @realDonaldTrump didn’t fire me — I fired Trump,” then cited the Kelly imbroglio as a reason.

“Very anxious to see the direction of the Trump campaign from here and the next round of credible polls,” tweeted @RogerJStoneJr, packing considerable innuendo in the word “credible.”

In a resignation letter obtained by MSNBC, Stone wrote that “the current controversies involving personalities and provocative media fights have reached such a high volume that it has distracted attention from your platform and overwhelmed your core message…With this current direction of the candidacy, I no longer can remain involved in your campaign.”

The Post had reported that Trump had fired his “longest serving adviser and confidant” by email on Friday, and that Trump had told the Post he was “cleaning house” and wanted to surround himself with “the best and most serious” people. Trump declined to apologize for the Megyn Kelly kerfuffle.

Stone continued his twitter battle later, posting, “The notion that I somehow need to get publicity for myself is really, really funny– he should do a google NEWS search.”

On Friday night, during a phone interview with CNN’s Don Lemon, Trump doubled down on Kelly, Fox and Fox pollster Frank Luntz, calling both Kelly and Luntz lightweights, and Luntz “a total dope” and “a wise guy.” Trump called Fox’s Chris Wallace “only a tiny fraction of Mike,” referring to Wallace’s late dad Mike Wallace of 60 Minutes.
