President Donald Trump on Friday announced White House deputy chief of staff Stephen Miller will be promoted to chief of staff, replacing Susie Wiles.

Miller will take over starting Monday, Trump said in a Truth Social post, praising his longtime aide as "one of my most trusted advisors."

Wiles, "who has done an outstanding job, will be moving over to the Trump Political Operation," the president wrote.

Trump revealed the stunning shake-up just three days after Democrats' landslide victory in the midterm elections, winning majority control of the House and Senate and scrambling the trajectory of Trump's last two years in office.
