Donald Trump will reportedly announce top immigration adviser Stephen Miller as his new deputy chief of staff for policy in the White House.

Miller will return with more influence than he had during the first Trump administration, where he served as a senior policy adviser, two sources familiar with the matter said. CNN.

Miller developed a reputation as an immigration hardliner who promoted white nationalist ideas. He was a key architect behind the family separation policy at the border.

Trump spokesperson Karoline Leavitt did not confirm the news to CNN, saying only: “These decisions will be announced as they are made.”
