Trump replaces White House chief of staff following midterm defeats

US President Donald Trump has announced a major White House shake-up, naming close political ally and adviser Stephen Miller as the new White House chief of staff. Miller is scheduled to move into the new role on Monday, replacing current chief of staff Susie Wiles.

The leadership change comes just days after the Republican party suffered sweeping defeats in the midterm elections. Some reports describe the outcome as a landslide victory for Democrats, with the opposition party winning majority control of both the House and the Senate.

Susie Wiles, who is stepping down from the position, previously made history as the first woman to serve in the role. Meanwhile, reports note that her successor, Stephen Miller, has been recognized as a close political ally of Trump and is described by some as a controversial aide and policy architect.
