Stephen Miller named White House Chief of Staff

Following historic Republican losses in the midterm elections, Donald Trump has replaced his chief of staff, Susie Wiles, with her deputy Stephen Miller, the architect of his administration’s immigration crackdown. Wiles had been seen by some as a stabilising force in the White House, but with Democrats now controlling both chambers of Congress, Trump is reportedly seeking a more aggressive approach to pushing his agenda.
