President Donald Trump announced on Truth Social that Stephen Miller will replace Susie Wiles as White House Chief of Staff following the 2026 midterm elections. The appointment signals an assertive executive posture even as Democratic congressional majorities take office on January 3, 2027. Miller previously served as Homeland Security Advisor and Deputy Chief of Staff for Policy while advancing strict anti-immigration policies across the administration.
Executive authority remains central to his doctrine. His broad policy platform includes supporting protective tariffs, backing Health and Human Services Secretary Robert F. Kennedy Jr., and proposing the suspension of habeas corpus under Article I of the Constitution. Miller also urged invoking the Insurrection Act to deploy federal troops following the deaths of Renee Good and Alex Pretti during Minneapolis protests. Though White House lawyer Will Scharf previously authored a confidential memo opposing habeas corpus suspension, Miller's structural elevation leaves further testing of executive emergency powers likely.
