report Tuesday from the Southern Poverty Law Center (SPLC) showed excerpts from leaked emails by prominent Trump policy adviser Stephen Miller that pushed white nationalist propaganda on right-wing news outlet Breitbart. The emails were provided by Katie McHugh, a former Breitbart reporter who frequently corresponded with Miller. 

SPLC reviewed 900 of these emails that were sent between March 4, 2015 and June 26, 2016. Roughly 80% of the emails sent from Miller to McHugh focused on race or immigration, with Miller often focusing on crimes committed by nonwhites. 

Miller, a top figure in President Trump's "America First" agenda, sent McHugh a story from white nationalist website VDare, and also recommended that Breitbart publish a story on the "Camp of The Saints." The 1973 novel by Jean Raspail focuses on a "great replacement" theory which suggests that immigrants from Africa and Asia will take over France.  

When asked by SPLC about Miller's contacts with Breitbart editors, Breitbart spokeswoman Elizabeth Moore defended the site. "The SPLC claims to have three- to four-year-old emails, many previously reported on, involving an individual whom we fired years ago for a multitude of reasons, and you know why we fired her. Having said that, it is not exactly a newsflash that political staffers pitch stories to journalists – sometimes these pitches are successful, sometimes not," she said.  

As for "Camp of the Saints," Moore alleged that "no one in our senior management has read the book." 

McHugh was fired from Breitbart in 2017 after she claimed on Twitter that there would be no terrorism in the U.K. if it weren't for Muslim immigrants. During her tenure, she posted multiple racist tweets and engaged in friendly Twitter banter with Donald Trump Jr.

Since her dismissal, she has felt regret for the controversial statements she made and has called the alt-right movement "evil."

Breitbart was launched in 2007 by Andrew Breitbart, a conservative commentator. The website's former executive chairman Steve Bannon became a policy adviser to President Trump. Bannon was fired by Trump in August 2017 after the Unite the Right white nationalist rally in Charlottesville, Virginia, drew violence, with three people dead and dozens injured.
