Donald Trump is naming longtime adviser Stephen Miller, an immigration hardliner, to be the deputy chief of policy in his new administration, reports the AP. Vice President-elect JD Vance posted a message of congratulations on Monday to Miller on X and said, "This is another fantastic pick by the president." Miller was a senior adviser in Trump's first term and has been a central figure in many of his policy decisions, notably his move to separate thousands of immigrant families as a deterrence program in 2018. Miller helped craft many of Trump's hardline speeches and plans on immigration. As CNN reports, Miller has said that a second Trump term would see 10 times as many deportations—to the tune of more than a million per year.
