Hatewatch reviewed more than 900 previously private emails Miller sent to Breitbart editors from March 4, 2015, to June 27, 2016. Miller does not converse along a wide range of topics in the emails. His focus is strikingly narrow – more than 80 percent of the emails Hatewatch reviewed relate to or appear on threads relating to the subjects of race or immigration. Hatewatch made multiple attempts to reach the White House for a comment from Miller about the content of his emails but did not receive any reply.

Katie McHugh, who was an editor for Breitbart from April 2014 to June 2017, leaked the emails to Hatewatch in June to review, analyze and disseminate to the public. McHugh was 23 when she started at Breitbart and also became active in the anti-immigrant movement, frequently rubbing shoulders with white nationalists. McHugh was fired from Breitbart in 2017 after posting anti-Muslim tweets. She has since renounced the far right.

Miller sent a story from the white nationalist website VDARE to McHugh on Oct. 23, 2015, the emails show. White nationalist Peter Brimelow founded VDARE in 1999. The website traffics in the “white genocide” or “great replacement” myth, which suggests that nonwhite people are systematically and deliberately wiping white people off the planet.

McHugh started the email conversation by asking if Hurricane Patricia could drive refugees into the United States. The hurricane battered parts of Central America, Mexico and Texas, and the media heavily covered the storm. Miller replied to her by underscoring the possibility that Mexican survivors of the storm could be given temporary protected status (TPS), a George H.W. Bush-era policy that would enable them to live and work in the United States for a limited stay:

Miller recommended in a Sept. 6, 2015, email that Breitbart write about “The Camp of the Saints,” a racist French novel by Jean Raspail. Notably, “The Camp of the Saints” is popular among white nationalists and neo-Nazis because of the degree to which it fictionalizes the “white genocide” or “great replacement” myth into a violent and sexualized story about refugees.

Miller refers to President Calvin Coolidge multiple times in emails to Breitbart. Coolidge signed the Immigration Act of 1924. The legislation was based on eugenics and severely limited immigration from certain parts of the world into the United States. White nationalists lionize Coolidge, in part for his remarks condemning race mixing.

In “Mein Kampf,” Hitler portrayed the U.S. law as a potential model for the Nazis in Germany. James Q. Whitman, the Ford Foundation professor of comparative and foreign law at Yale Law School, noted this detail in his book “Hitler’s American Model: The United States and the Making of Nazi Race Law.”

Miller brings up Coolidge on Aug. 4, 2015, in the context of halting all immigration to America. Garrett Murch, who also was an aide to Sessions, starts the conversation by emailing McHugh, Miller and three other Breitbart employees, including Hahn, to note something he heard on a right-wing talk radio show:

[...]

Another example of Miller mentioning Coolidge happens Sept. 13, 2015, when he criticizes Republican Sens. John McCain and Lindsey Graham for appearing too sympathetic to refugees. Miller sends an email to McHugh and Hahn with the subject, “Tucker asks McCain, Graham how refugees are good for Americans,” with a transcript of a discussion between the two senators and Tucker Carlson of Fox News.

[...]

Miller helped shape one of McHugh’s stories for Breitbart titled “Ted Kennedy’s Real Legacy: 50 Years of Ruinous Immigration Law,” the emails show. The story focused on the legacy of the Hart-Celler Act from the perspective that the removal of racial quota laws harmed the country. Miller flagged the story idea to McHugh:

[...]

In his emails, Miller uses slang and rhetoric about immigration that would be familiar to people who read white nationalists discussing the “great replacement” conspiracy theory. He refers to demographic changes brought about by immigration as “new America” multiple times in the emails. It’s a phrase VDARE sometimes uses.
