Mark Milley Thought Stephen Miller Was 'Rasputin Character': Book

General Mark Milley, chairman of the Joint Chiefs of Staff, reportedly considered senior White House adviser Stephen Miller to be a "Rasputin character," according to a book released on Tuesday.

The claim comes from Pulitzer Prize-winning Washington Post journalists Carol Leonnig and Philip Rucker in their book I Alone Can Fix It: Donald J. Trump's Catastrophic Final Year.

In the book, Leonnig and Rucker write about an alleged exchange between Milley and Miller regarding the deployment of the military against those protesting over the death of George Floyd.

The exchange between Milley and Miller was previously reported by The Wall Street Journal's Michael Bender in his book Frankly, We Did Win This Election: The Inside Story of How Trump Lost.

Milley's comparison of Miller to the famous Russian mystic appears to be a new detail.

Miller served as senior adviser for policy and White House director of speechwriting and has continued to support Trump since leaving the administration.

According to Leonnig and Rucker, Milley considered Miller to be "a Rasputin character, always whispering devilish ideas in the king's ear."

Grigori Rasputin is a controversial figure from Russian history who is often portrayed as a villain. He was a key figure at the court of the last tsar, Nicholas II, and had significant influence over the imperial family.

The term "Rasputin" has come to mean someone who nefariously influences a person in a position of power and the name has been applied to a number of officials around the world.

Leonnig and Rucker's book also recounts an alleged meeting, reported earlier this year by Bender, about the antiracism protests across the country in reaction to the killing of George Floyd in Minnesota.

Former President Donald Trump, former Attorney General William Barr, Miller and Milley were reportedly present to discuss the issue.

Miller reportedly urged then President Trump to deploy the military in order to shut down the protests but Milley was opposed to the idea.

Milley replied: "Shut the [expletive] up, Stephen."

"They're not burning the [expletive] country down," the general said, according to Leonnig and Rucker's account.

Former President Trump recently denied that he had discussed deploying the military with Milley in January after extracts from I Alone Can Fix It were published claiming Milley and other senior military officials were worried that Trump might try to stage a coup or commit some other illegal action.

"Despite the fact that the 2020 Presidential Election was Rigged and Stolen, and while numerous people, including the outside public, were saying we should bring in the Military, I never even gave it a thought," Trump said in a statement.

"Never once did I have a discussion with [Milley] about bringing in the Military, or a 'coup,'" he added.

Newsweek has asked the Joint Chiefs of Staff for comment. Newsweek has sought comment from Stephen Miller through his legal group, America First Legal.
