Yes, he is.

The Trump White House tried to defend top aide Stephen Miller from his newly exposed links to white nationalism by claiming that repeating his own words back to him is anti-Semitic, saying that reporting on Miller’s emails promoting white nationalist garbage “is clearly a form of anti-Semitism to levy these attacks against a Jewish staffer."

The White House official who gave the statement to Axios wouldn’t explain how Hatewatch’s report on Miller’s communications is a bigoted attack on Miller, but even they’re not standing by their ridiculous claim because the unnamed official made the comment to Axios on background, reporter Zach Basu tweeted.

And they should be embarrassed, because Miller is in fact a white supremacist, and his emails—many sent from a government account during his time working for then-Sen. Jefferson Beauregard Sessions III—back that up, touching on “white nationalist websites, a ‘white genocide’-themed novel in which Indian men rape white women, xenophobic conspiracy theories and eugenics-era immigration laws that Adolf Hitler lauded in Mein Kampf,” Hatewatch said. Charming.

Democratic leaders who had previously been lambasted by pearl-clutching Republicans for pointing out the obvious about Miller and his radicalism have now reiterated their calls for Miller to exit the White House. “As I said earlier this year: Stephen Miller is a white nationalist. And now we have the emails to prove it,” tweeted Rep. Ilhan Omar. “This type of racism and hatred has no place in our government. Miller needs to step down. Now.”
