Stephen Miller Named Trump's Chief of Staff, Replacing Susie Wiles

President Donald Trump announced Friday that Stephen Miller will become White House Chief of Staff starting Monday, replacing Susie Wiles in the most significant administration shift following Tuesday's midterm elections where Republicans lost control of both congressional chambers. Wiles, who was diagnosed with breast cancer earlier this year and completed chemotherapy while serving, will be reassigned to oversee the Trump Political Operation, according to Trump's Truth Social post. She stated it was "an honor of a lifetime" to serve, adding her commitment to the president "never will" change. Miller, currently Deputy Chief of Staff, is the central architect of Trump's immigration agenda, including mass deportations and border closure policies. He previously co-wrote the Muslim ban and advocated ending DACA during the first Trump administration.
