Trump announces major White House shake-up: Deputy Chief of Staff Stephen Miller will take over as White House chief of staff on Monday, November 9, while current chief of staff Susie Wiles will move to Trump's political operation. Trump posted on Truth Social on November 6 that Miller was “one of his most trusted advisers” and thanked Wiles for her service. This is the White House's first major personnel change three days after Republicans lost the midterm elections. Wiles later confirmed on X that November 6 was her last day as chief of staff.
