Trump expected to announce Stephen Miller as deputy chief of staff
President-elect Donald Trump is expected to announce Stephen Miller, an immigration hard-liner and one of his senior advisers, will become his deputy chief of staff for policy, multiple sources familiar with the matter told ABC News.
It's not clear when Trump plans to formally announce the job, the sources said.
Miller worked in the first Trump administration and played a key role in crafting immigration policies -- including those that resulted in thousands of families being separated at the border.
