President Donald Trump announced Friday that Stephen Miller will serve as the next White House Chief of Staff, effective Monday. The announcement marks the most significant shift in the administration's operations since Republicans lost control of both chambers of Congress in Tuesday's midterm elections.
Susie Wiles, the current Chief of Staff and a longtime political operative for Trump, will be reassigned to oversee "the Trump Political Operation," according to Trump's post on Truth Social. Trump thanked Wiles for her service, stating she "has done a great job."
Wiles, 69, was diagnosed with breast cancer earlier this year and underwent six months of chemotherapy while managing her White House duties. She announced in September that she is cancer-free following positive pathology results.
In a statement posted on X, Wiles called her service as Chief of Staff an "honor of a lifetime" and expressed gratitude for her colleagues. "While my role may be changing, my commitment to the President and the mission never will," she said.
Miller previously served as White House Deputy Chief of Staff during Trump's second term. He is recognized as a central figure in Trump's immigration agenda, which included mass deportations and efforts to close the U.S.-Mexico border. Miller also oversaw Trump's homeland security agenda alongside border czar Tom Homan.
During the first Trump administration, Miller was a senior advisor to the president and director of speechwriting. In that capacity, he co-wrote the policy that led to the ban on travelers from several Muslim-majority countries and advocated for the gradual end of the Deferred Action for Childhood Arrivals (DACA) program.
