President Donald Trump is “the most transformative political leader in American history,” incoming White House chief of staff Stephen Miller said Friday as he prepares to succeed outgoing Susie Wiles.
Trump announced that Miller would take over as deputy chief of staff for policy on Monday, with Wiles transferred to Trump’s political action department, and Miller posted praise on X.
Miller has consistently sided with Trump since the 2016 campaign. He praised the president for saving the country and pledged to fight for his agenda. In the same statement, he thanked Wiles for his service and called the appointment the pinnacle of his career.
Trump called Miller “one of my most trusted advisors” on “Truth Social” and thanked Wiles for his work.
Miller, 41, is a veteran of the first class. He served as a senior adviser and speechwriting director under Trump, and after leaving office ran the conservative organization America First Law. He returns in 2025 as deputy chief of staff for policy and homeland security adviser. In this position, he pushed for deportations and border crackdowns in his second term.
Axios reported, citing unnamed sources, that Wiles had questioned Miller’s hard-line immigration strategy and opposed the administration’s war on Iran. A Trump adviser told the outlet that “Stephen is a wartime adviser” created for the coming conflict with a Democratic Congress.
Wiles announced his exit on “The X,” calling the job “the honor of a lifetime” and saying Trump made the right choice with Miller. She guided his 2024 campaign before taking office in January 2025 and stayed on through the breast cancer diagnosis disclosed in the spring.
White House communications director Steven Cheung supported X’s choice, writing, “No one supports the Trump agenda more than Steven Cheung.”
Democrats won control of both houses of Congress in Tuesday’s midterm elections. Three weeks ago, Trump said there was “zero chance” he would succeed Wiles and dismissed reports naming Miller as a possible successor.
