(FILES) US Secretary of State Marco Rubio and White House Chief of Staff Susie Wiles talk during a roundtable to "save college sports" in the East Room of the White House in Washington, DC, on March 6, 2026. President Donald Trump on November 6, 2026, named Stephen Miller as his new chief of staff, promoting the architect of his hardline migration policy after the Republican Party's brutal US midterms defeat. Miller will replace current White House chief of staff Susie Wiles as of Monday, Trump said on his Truth Social network, thanking Wiles for an "outstanding job."
