President-elect Trump is expected to pick Stephen Miller as deputy chief of staff for policy in his administration.
Vice President-elect JD Vance posted a message of congratulations to Miller on X Monday morning.
"This is another fantastic pick by the president," Vance wrote, following a CNN report about Trump's pick.

Miller was a senior adviser in Trump’s first term. He helped craft many of Trump’s hard-line speeches and plans on immigration.
Since Trump left office, Miller has served as the president of America First Legal, an organization of former Trump advisers fashioned as a conservative version of the American Civil Liberties Union, challenging the Biden administration, media companies, universities and others over issues such as freedom of speech and religion and national security.
