Stephen Miller's immigration hard-line record shapes his new White House chief of staff role

Stephen Miller, President Trump's new White House chief of staff, is known for his harsh language and unrelenting bombast, attracting outsize attention from supporters and critics alike. He has been behind many of the administration's signature domestic policy initiatives, especially its sweeping crackdown on immigration. Miller has described migrants as invaders, defended family separation policies, and suggested suspending habeas corpus to expand deportation powers. He has also made controversial statements about seizing Greenland, taking over Venezuela's oil reserves, and criticizing Democrats as a "domestic extremist organization." His record is likely to be scrutinized by Democrats in his powerful new role as he leads Trump's White House through a lame-duck period after the Republican Party lost both houses of Congress. Miller has also expressed skepticism about childhood vaccines, contradicting CDC research.
