Stephen Miller’s appointment shows Trump hasn’t learned his lesson on immigration

What happened: Trump named Stephen Miller, the architect of his administration's aggressive immigration policies, as chief of staff, after voters rebuked Republican candidates in the midterms. Key numbers: Miller, 41, devised the first-term zero tolerance policy that separated more than 5,600 children at the border. Why it matters: Advocates and Democratic lawmakers say the promotion signals an acceleration of mass deportations. Representative Robert Garcia promised to investigate Miller, and Senator Alex Padilla pledged oversight, subpoenas and leverage over federal funding.
