Stephen Miller named White House Chief of Staff

Miller, who served as the architect of Trump's administration's immigration crackdown, will take over from Wiles, who had been seen by some as a stabilizing force in the White House.

With Democrats now controlling both chambers of Congress, Trump is reportedly seeking a more aggressive approach to pushing his agenda through the legislative process.

The reshuffle comes as Trump prepares for a potentially challenging legislative session where he will need to navigate a divided government to advance his policy priorities.
