From The Chronicle (Duke University):
Stephen Miller, White House senior advisor […] drew a firestorm of media attention this week after hundreds of his emails with a former Breitbart editor were reported by the Southern Poverty Law Center.
Miller, an immigration hardliner who was reportedly an architect of President Donald Trump’s controversial “Muslim ban,” sent the emails to Katie McHugh, then an editor at Breitbart, in 2015 and 2016. The SPLC report paints a picture in which Miller would send information and story ideas—sometimes citing VDare, which has published work by white nationalists, and InfoWars, which is known for promoting conspiracy theories—to McHugh, who then often wrote about the topics for Breitbart.
