Known for his stance against immigration, Miller is the man behind some of Trump’s most aggressive policies on the issue. Some of the policies he pushed include family separation at the southwestern border and the travel ban on seven countries, five of which have a Muslim majority. He is also an advocate of building Trump’s long-proposed wall along the U.S.-Mexico border. Rep. Ilhan Omar (D-Minn.) earlier this month called Miller a white nationalist, citing CNN and Washington Post reports that link him to Trump’s decision to withdraw Ronald Vitiello’s nomination to be the next head of Immigration and Customs Enforcement. Vitiello, a 30-year veteran of the U.S. Border Patrol, apparently did not endorse shutting down the southern border, as Miller had wanted.

Stephen Miller is a white nationalist. The fact that he still has influence on policy and political appointments is an outrage. https://t.co/7NyMDgojd7 — Ilhan Omar (@IlhanMN) April 8, 2019
