While in college he was friends with and mentored by the notorious white supremacist Richard Spencer. Together, Miller and Spencer collaborated on bringing right-wing ideologues to Duke University, where Miller was a student.

White supremacists are gleeful and inspired by Stephen Miller's role in the Trump administration. White supremacists know that Miller and Trump share their agenda, whatever caveats they may offer in public.

While in high school in the famously liberal community of Santa Monica, California, Miller harassed black and brown students.

Miller also reportedly stopped being friends with one of his childhood friends because the latter was Hispanic. He once gave a viciously racist speech in which he mocked and belittled the nonwhite janitorial and other support staff at his high school.
